Mechanistic insights into the Rh(i)-catalyzed transannulation of 1,2,3-thiadiazoles with alkenes, alkynes, and nitriles: Does the intermediacy of alpha-thiavinyl Rh-carbenoids play an important role?

Density functional theory (DFT) calculations were performed to gain an in-depth mechanistic understanding of the Rh(i)-catalyzed transannulation of 1,2,3-thiadiazoles with alkenes, alkynes, and nitriles. Computational results indicate that the denitrogenation of 1,2,3-thiadiazoles promoted by the Rh(i) catalyst may not afford the commonly proposed alpha-thiavinyl Rh-carbenoid intermediate. Instead, the four-membered cyclometalated Rh(iii) complex is suggested to be the key intermediate, which could be formed via the cleavage of the S-N bond of 1,2,3-thiadiazoles to generate a six-membered cyclometalated Rh(iii) complex followed by N-2 extrusion. The easy chelation of the S atom with Rh is mainly responsible for the favorable formation of the four-membered cyclometalated Rh(iii) intermediate. Next, the substrates alkenes, alkynes, and nitriles could undergo migratory insertion with the four-membered rhodacycle followed by reductive elimination to furnish the corresponding products. The origins of divergent regioselectivities for the Rh(i)-catalyzed transannulation of 1,2,3-thiadiazoles with alkenes, alkynes, and nitriles are discussed, respectively, which are not only determined by the feasible migratory insertion pathway, but also by the feasibility of the subsequent reductive elimination.

Study of Thermal Insulation Performance of Layered Jute Nonwoven: A Sustainable Material

An eco-friendly sustainable thermal insulator has been developed as a replacement of some commercially available manmade materials to control heat transfer in case of buildings, and semi-permanent/temporary structures. Jute felts were prepared by needle pinching of fiber fleece. It is a self-sustained semi-rigid structure and could be placed on various surface profiles of the building/structure due to its balanced flexural rigidity and surface property of fiber. Effect of areal density, thickness, and number of layers of jute felt on its major thermal insulation property parameters were studied. Some major structural parameters of felts viz., pore size, bulk density, and air fraction as gas pockets in fibrous structure were analyzed and correlated with the insulation property. Felt having 500 g/m(2) areal density showed best specific thermal insulation performance. When it was used in four layers, its thermal insulation value reached up to 341 m(2)K/kW, which is much comparable to those of glass wool (320 m(2)K/kW), nitrile rubber (320 m(2)K/kW), and polystyrene (381 m(2)K/kW) insulators. The cost of jute felts ($ 2.81 for four layers of 500 g/m(2)) was much comparable to synthetics ($2.9 for glass wool and $ 2.7 for nitrile rubber) of similar thermal insulation value. It also facilitates remarkable saving of costly floor space to the extent of 28% as compared to synthetics. The ease of tailorability of jute felt was also studied by measuring drapability, tensile strength, tear strength, and energy required to cut the felt. Inherent multiple lumens within fiber structure, partial anisotropy of polymer chains, and innumerable tiny gas pockets within the felt structure are the major reasons for the high thermal insulation of jute felt.

alpha-Alkylation of arylacetonitriles with primary alcohols catalyzed by backbone modified N-heterocyclic carbene iridium(I) complexes

A series of backbone-modified N-heterocyclic carbene (NHC) complexes of iridium(I) (1d-f) have been synthesized and characterized. The electronic properties of the NHC ligands have been assessed by comparison of the IR carbonyl stretching frequencies of the in situ prepared [IrCl(CO)(2)(NHC)] complexes in CH2Cl2. These new complexes (1d-f), together with previously prepared 1a-c, were applied as catalysts for the alpha-alkylation of arylacetonitriles with an equimolar amount of primary alcohols or 2-aminobenzyl alcohol. The catalytic activities of these complexes could be controlled by modifying the N-substituents and backbone of the NHC ligands. The NHC-Ir-I complex 1f bearing 4-methoxybenzyl substituents on the N-atoms and 4-methoxyphenyl groups at the 4,5-positions of imidazole exhibited the highest catalytic activity in the alpha-alkylation of arylacetonitriles with primary alcohols. Various alpha-alkylated nitriles and aminoquinolines were obtained in high yields through a borrowing hydrogen pathway by using 0.1 mol% 1f and a catalytic amount of KOH (5 mol%) under an air atmosphere within significantly short reaction times.

Rotaxane-Based Difunctional Nitrile N-Oxide Crosslinker: Synthesis and Direct Introduction of Movable Crosslinking Points into Ethylene-Propylene-Butadiene Monomer (EPDM) Rubber

Incorporation of rotaxane scaffolds into the crosslinking points of polymer networks significantly affects their rheological and mechanical properties. The present study involves the synthesis of a new rotaxane-type crosslinker containing nitrile N-oxide functional groups on both the axle and wheel components. The prepared crosslinker is highly reactive; however, it can be isolated and applied in the crosslinking reaction of a commercially important polymer, namely ethylene-propylene-butadiene monomer rubber (EPDM), in the absence of additives and catalysts. Tensile tests reveal that compared to a network containing conventional crosslinking points, both breaking strength and strain of the network structure prepared herein are improved due to the incorporation of movable crosslinking points. The synthesized network structure also exhibits five times higher fracture energy. The developed post-crosslinking methodology for the direct introduction of movable crosslinking points into pre-formed polymers will be valuable in the production of rotaxane materials for various applications.

Method for the Preparation of N-protected beta-Cyano L-alanine Tertiary Butyl Esters

Here we report a simple, efficient and scalable one-pot procedure for the synthesis of N-protected beta-cyano L-alanine tertiary butyl esters from N-protected L-asparagines. Reaction of N-protected L-asparagines with 2.2 equivalents of (Boc)(2)O and catalytic amount of N,N-dimethylamino pyridine (DMAP) in tertiary butanol at room temperature resulted N-protected beta-cyano L-alanine tertiary butyl esters. We also synthesized N-protected beta-cyano L-alanines from the obtained crude N-protected beta-cyano L-alanine tertiary butyl esters without column chromatography on gram scale in good yields. Control experiments gave the corresponding nitrile acids over the tertiary butyl esters. Later, we synthesized nitrile containing dipeptides by coupling N-Boc-beta-cyano L-alanine 4 a with amino acid methyl ester hydrochlorides.

Mapping Io’s Surface Composition With Juno/JIRAM

The surface composition of Io is dominated by SO2 frost, plus other chemical species identified or proposed over the past decades by combining Earth-based and space-based observations with laboratory data. Here we discuss spectroscopic data sets of Io obtained by the Jovian InfraRed Auroral Mapper (JIRAM) spectro-imager onboard Juno in nine orbits, spanning a 3-year period. We display average spectral profiles of Io in the 2-5 mu m range, and we use band depths derived from those profiles to map the geographic distribution of SO2 frost and other spectral features. This data set allows for an similar to 22% surface coverage at 58 to 162 km/px and in a broad range of latitudes. Our results confirm the broadly regional SO2-frost trends already highlighted by Galileo/NIMS. Io’s average spectral profiles as well as the mapping of the 4.47-mu m band also confirm that SO2 exists in the (SOO)-S-32-O-16-O-18 isotopic form. Surprisingly, the mapping performed by JIRAM shows that the absorption band at 2.1 mu m is unrelated to SO2 frost, while we map for the first time the depth of the 2.65-mu m band, highlighting regions enriched in this absorber, possibly H2S. JIRAM data confirm that the 3.92-mu m band, likely due to Cl2SO2, is largely related to the SO2 distribution. The correlation between Cl2SO2 and ClSO2, possibly revealed at 4.62 mu m, is not equally clear. The simultaneous presence of two very weak spectral features at 4.55 and 4.62 mu m suggests that nitrile compounds or tholins may also be present on the surface. Plain Language Summary The surface of Io is mainly covered by sulfur dioxide (SO2) frost and by other chemical species. The Jovian InfraRed Auroral Mapper (JIRAM) instrument onboard the NASA Juno spacecraft, in orbit around Jupiter, can occasionally observe the Galilean satellites through its slit spectrometer (2-5 mu m range). We show average spectral profiles of Io obtained by JIRAM in a 3-year period, mapping the geographic distribution of SO2 frost and other spectral features. Our results confirm the broadly regional SO2-frost trends already highlighted in the past. Our data confirm that SO2 exists in multiple isotopic forms. Surprisingly, the mapping performed by JIRAM shows that the absorption band at 2.1 mu m is unrelated to SO2 frost. We map for the first time the depth of the 2.65-mu m band, which might be related to hydrogen sulfide (H2S). We also highlight regions enriched in this absorber. We confirm that the 3.92-mu m band, ascribed to sulfuryl chloride (Cl2SO2), is largely correlated with the SO2 distribution. The correlation between Cl2SO2 and ClSO2, possibly revealed at 4.62 mu m, is not equally clear. The simultaneous presence of two very weak spectral features at 4.55 and 4.62 mu m suggests that nitrile compounds or tholins may also be present on the surface.

Recent advances in C-CN and C-H bond activation of green nitrile (MeCN) for organo-complexation, cyanation and cyanomethylation

The use of green and inexpensive organic nitrile (MeCN) as a cyano and cyano-methyl source for organo-complexation, cyanation, and cyanomethylation is reviewed. In recent decade, a lot of developments have been made to realize the possibility of using a green cyanide source (MeCN) for cyanation, and this CN source has been used as, for example, a slow dosage cyanide source that could solve the problem of using metal cyanides (K-4[Fe(CN)(6)], Zn(CN)(2), KCN, CuCN, NaCN), which (1) tend to cause rapid deactivation of the catalyst and (2) are notoriously toxic, producing highly toxic HCN gas in reactions. In view of these problems, here we attempted to discuss new catalyst systems to achieve the cyanation of various aromatic hydrocarbons, such as aryl halides, aryl boronic acids, aryl carboxylic acids, indoles, diazoarenes, aryl alkynes, aryl sulfonamides, and directing group substituted arenes, under variety of reaction parameters. Moreover, acetonitrile is used as the carbon pro-nucleophile in C-C bond formation, which involves complications usually associated with the catalyst active mode or its resting state. This review demonstrates a set of innovations for practical usageviadirect complexation, cyanation and cyanomethylation methodologies.

Highly concentrated nitrile functionalized disiloxane – LiFSI based non-flammable electrolyte for high energy density Li metal battery

High energy density and safety are key issues of Li metal battery (LMB). A thin Li anode coupling with high voltage/ high capacity cathode (NCM811) can increase the energy density of Lithium batteries. We have developed a fire retar dant disiloxane based highly concentrated electrolyte which makes a coordinated Li+-FSI–Solvent cluster to produce stable interphase on electrodes. This electrolyte shows reduced reactivity towards Li metal anode. The oxidation stability of electrolyte is high (5 V) and also shows less Al corrosion. The synergistic effect of additive makes inorganic ‘LiF’-rich dendrite free interphase. SEM analysis confirms dendrite free surface morphology. A Li metal full cell is fabricated with thin Li anode (20 mu m, 4.12 mAh/cm(2)) and NCM811 cathode with moderate active material loading (1.1 mAh/cm(2)), providing a high energy density of 614 Wh kg(-1) (based on total weight of anode and cathode excluding current collectors).

8-cyanobenzothiazinone analogs with potent antitubercular activity

8-Nitrobenzothiazinones (BTZs) exemplified by macozinone are a new class of antitubercular agents with exceptionally potent activity. The aryl nitro group has been considered indispensable for activity since this is bioactivated within mycobacteria by the flavoenzyme DprE1 to a reactive nitroso metabolite that covalently labels Cys387. However, the aryl nitro group is a potential liability with regards to safety, stability, and resistance. In this paper, we introduced a nitrile as a bioisosteric replacement of the nitro group, which we hypothesize can maintain a similar covalent mechanism of inhibition, but mitigate against the aforementioned concerns. 8-cyanobenzothiazinone 1d displayed potent antitubercular activity with an MIC of 130 nM and had an improved volume of distribution in mice that increased the intrinsic half-life by twofold compared to macozinone. Analysis of the C-2 substituent of 1d revealed similar structure-activity relationships as observed for macozinone. Overall, the results confirm the 8-nitro group of benzothiazinones can be successfully replaced with a nitrile to retain useful activity and favorable pharmacokinetic properties. [GRAPHICS] .
