Catalytic Direct Construction of Cyano-tetrazoles

Cyano-tetrazole is the first reported compound that bears four nitrogen atoms in a single five-membered ring. This unique molecular scaffold has long been ignored after its discovery in 1885, mainly attributed to the scarcity of available synthetic methods. Indeed, the most popular approach to tetrazoles (that is the cycloaddition reaction between nitriles and azides) has inevitably excluded the possibility of introducing valuable cyano groups to decorate the final heterocyclic cores. Here, we describe a completely different disconnection strategy to the long time-pursued cyano-tetrazoles via a simple, direct, and practical cycloaddition transformation between readily accessible aryl diazonium salts and diazoacetonitrile. This method provides both regioisomers of disubstituted tetrazoles from the same set of starting materials in a metal cation controlled fashion.

Highly Productive alpha-Alkylation of Ketones with Alcohols Mediated by an Ir-Oxalamidato/Solid Base Catalyst System

An Ir-oxalamidato complex in combination with a solid base (e.g., magnesium aluminometasilicate/Ca(OH)(2)) significantly improved the catalyst productivity in alpha-alkylation of methyl ketones with primary alcohols. Optimization through systematic variation of the oxalamidato ligand led to a practical turnover number (TON) of 10 000-40 000.

Design and Optimization of an Acyclic Amine Series of TRPV4 Antagonists by Electronic Modulation of Hydrogen Bond Interactions

Investigation of TRPV4 as a potential target for the treatment of pulmonary edema associated with heart failure generated a novel series of acyclic amine inhibitors displaying exceptional potency and PK properties. The series arose through a scaffold hopping approach, which relied on use of an internal H-bond to replace a saturated heterocyclic ring. Optimization of the lead through investigation of both aryl regions revealed approaches to increase potency through substituents believed to enhance separate intramolecular and intermolecular H-bond interactions. A proposed internal H-bond between the amine and neighboring benzenesulfonamide was stabilized by electronically modulating the benzenesulfonamide. In the aryl ether moiety, substituents para to the nitrile demonstrated an electronic effect on TRPV4 recognition. Finally, the acyclic amines inactivated CYP3A4 and this liability was addressed by modifications that sterically preclude formation of a putative metabolic intermediate complex to deliver advanced TRPV4 antagonists as leads for discovery of novel medicines.

Disinfection technology and strategies for COVID-19 hospital and bio-medical waste management

The isolation wards, institutional quarantine centers, and home quarantine are generating a huge amount of biomedical waste (BMW) worldwide since the outbreak of novel coronavirus disease-2019 (COVID-19). The personal protective equipment, testing kits, surgical facemasks, and nitrile gloves are the major contributors to waste volume. Discharge of a new category of BMW (COVID-waste) is of great global concern to public health and environmental sustainability if handled inappropriately. It may cause exponential spreading of this fatal disease as waste acts as a vector for SARS-CoV-2, which survives up to 7 days on COVID-waste (like facemasks). Proper disposal of COV1D-waste is therefore immediately requires to lower the threat of pandemic spread and for sustainable management of the environmental hazards. Henceforth, in the present article, disinfection technologies for handling COV1D-waste from its separate collection to various physical and chemical treatment steps have been reviewed. Furthermore, policy briefs on the global initiatives for COVID-waste management including the applications of different disinfection techniques have also been discussed with some potential examples effectively applied to reduce both health and environmental risks. This article can be of great significance to the strategy development for preventing/controlling the pandemic of similar episodes in the future. (C) 2020 Elsevier B.V. All rights reserved.

Polymer-Supported Fe-Phthalocyanine Derived Heterogeneous Photo-Catalyst for the Synthesis of Tetrazoles Under Visible Light Irradiation

Herein, a polymer supported Fe-Phthalocyanine entangled with carboxyl functionalized benzimidazolium moiety (PSFePcCFBM) explored as heterogenous photocatalyst, for regioselective synthesis of 1H-tetrazoles from sodium azide and other affordable substrates. The PSFePcCFBM displayed good to excellent yield of the product (79-91%) under visible light (5 W) irradiations using home-made photoreactor. The NaN3 acts as a nitrogen donor of tetrazoles ring as well as it convert aldehyde into isocyanide as one of the nitrogen sources. The catalyst could be recycled up to 5th run successfully without altering its catalytic activity. The small amount of the catalyst loading, extensive substrate range, ease of separation of the catalyst by simple filtration, less reaction time, simple workup procedure, and excellent product yield are the salient features of the investigated protocol.

Synthesis and characterization of epoxidized neem oil: A bio-derived natural processing aid for elastomer

Low cost and environment-friendly bio-oils are gaining market value as a plasticizer for elastomeric compounds. Unsaturated triglycerides of bio-oils can be easily modified in various ways, like epoxidation, esterification, and so on. In the present work, 15 mole percentage of the total double bond content of the neem oil (NO) was epoxidized by acetic acid-hydrogen peroxide system to synthesize epoxidized neem oil (ENO). NO and ENO were characterized by nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy and differential scanning calorimetry. The effect of ENO on the properties of nonpolar styrene butadiene rubber (SBR) and polar nitrile rubber (NBR) was investigated. Tear strength (69.9 N/mm), abrasion resistance index (ARI) (68.2) and hardness (64 shore A) of the SBR/ENO compound were comparable to the compound containing total distillate aromatic extract (TDAE) (values: 70.8 N/mm, 68.0 and 64 shore A respectively). Tensile strength and ARI of conventional NBR/dioctyl phthalate (DOP) compound were 24.9 MPa and 107 respectively, whereas NBR/ENO compound showed improved tensile strength (26.9 MPa), and ARI (138). Tear strength (83.4 N/mm) and hardness (74 shore A) of NBR/ENO were comparable to the tear strength (83.5 N/mm) and hardness (74 shore A) of NBR/DOP compound. Hence, the multifunctional additive property of ENO makes it a cheap and sustainable replacement of TDAE and DOP.

SOLEIL and ALMA views on prototypical organic nitriles: C2H5CN

The high resolution vibrational spectrum of ethyl cyanide (C2H5CN) has been investigated in the far-IR using synchrotron-based Fourier transform spectroscopy. The assignment was performed using the Automated Spectral Assignment Procedure (ASAP) allowing accurate rotational energy levels of the four lowest fundamental vibrations of the species, namely the v(13) = 1 @ 205.934099(8)cm(1), v(21) = 1 @ 212.141101(8)cm(1), v(20) = 1 @ 372.635293(15)cm(1), and v(12) = 1 @ 532.699617(16)cm(1) states, to be determined. The analysis not only confirms the applicability of the ASAP in the treatment of (dense) high-resolution infrared spectra but also reveals some of its limitations. Complementary to the infrared study, the pure rotational spectrum of C2H5CN was also studied in selected frequency ranges from 75 to 255 GHz. New observations of a prototypical high-mass star-forming region, G327.3-0.6, performed with the Atacama Large Millimeter Array show that vibrational satellites of C2H5CN can be very intense, of order several tens of Kelvin in units of brightness temperature.

Mining the Cambridge Database for theoretical chemistry. Mi-LJC: a new set of Lennard-Jones-Coulomb atom-atom potentials for the computer simulation of organic condensed matter

A set of 377 crystal structures extracted from the Cambridge Structural Database and matched to the experimental sublimation enthalpies of the corresponding materials is used to calibrate a new intermolecular potential field for organic compounds. The scheme includes usual R-6-R-12 Lennard-Jones dispersion-repulsion terms, with parameters for C, H, N, O, S and the halogens, fully transferable and unique for each atomic species without distinction among the hybridization states of carbon, or among valence states like carbonyl or ether oxygen or aza, nitro or nitrile nitrogen. This great economy in the number of parameters is countered by the need for using accurate coulombic terms over atomic point charges derived for each molecule from the fitting of the electrostatic potential (ESP method) of an ab initio MP2/6-31G** wavefunction. The potential scheme so derived, called Mi-LJC (Milano Lennard-Jones Coulomb), is able to reproduce the 377 sublimation enthalpies by the calculated lattice energies with an average percent deviation of 5% and a rmsd of 6.7 kJ mol(-1). The potential scheme is also tested and proved applicable for the Monte Carlo simulation of some organic liquids, as well as for the molecular dynamic simulation of liquids and crystals.

Ru-II and Ru-III Chloronitrile Complexes: Synthesis, Reaction Chemistry, Solid State Structure, and (Spectro)Electrochemical Behavior

The synthesis of [Ti6O4(OiPr)(8)(O2CPh)(8)] (3) and [RuCl(N equivalent to CR)(5)][RuCl4(N equivalent to CR)(2)] (4a, R = Me; 4b, R = Ph), [Ru(N equivalent to CPh)(6)][RuCl4(N equivalent to CPh)(2)] (5) and [H3O][RuCl4(N equivalent to CMe)(2)] (7a) is discussed. Crystallization of 5 from CH2Cl2 gave trans-[RuCl2(N equivalent to CPh)(4)] (6). The solid-state structures of 3, 4a,b, 5, 6 and 7a are reported. Complex 4b forms a 3D network, while 6 displays a 2D structure, due to pi-interactions between the benzonitrile ligands. The (spectro)electrochemical behavior of 4a,b and 6 was studied at 25 and -72 degrees C and the results thereof are compared with [NEt4][RuCl4(N equivalent to CMe)(2)] (7b) and [RuCl(N equivalent to CPh)(5)][PF6] (8). The electrochemical response of the cation and the anion in 4a,b are independent from each other. [RuCl(N equivalent to CR)(5)](+) possesses one reversible Ru-II/Ru-III process. However, [RuCl4(N equivalent to CMe)(2)](-) was shown to be prone to ligand exchange and disproportionation upon formation of either a Ru-IV and Ru-II species at 25 degrees C, while at -72 degrees C the rapid conversion of the electrochemically formed species is hindered. In situ IR and UV/Vis/NIR studies confirmed the respective disproportionation reaction products of the aforementioned oxidation and reduction, respectively.
