Schirmacher, Robert H. E.;Roesch, Daniel;Thomas, Franziska research published 《 Hexafluoroisopropanol as solvent and promoter in the Paal-Knorr synthesis of N-substituted diaryl pyrroles》, the research content is summarized as follows. An additive-free synthesis of challenging N-substituted aryl pyrroles from the often poorly soluble corresponding 1,4-diketones by means of the Paal-Knorr pyrrole synthesis is reported, making use of the unique properties of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) as a solvent and reaction promoter. This procedure offers simple execution and purification as well as easy scale-up and can be applied in the Paal-Knorr synthesis of a large number of structurally diverse pyrroles including the synthetically challenging tetra- and penta-substituted pyrroles in moderate to excellent yields. HFIP can also be used as solvent in the Paal-Knorr synthesis of furans and thiophenes; however, the solvent effect is more pronounced in the synthesis of pyrroles.

Sen, Partha Pratim;Roy, Vishal Jyoti;Raha Roy, Sudipta research published 《 Metal-free regioselective bromination of imidazo-heteroarenes: the dual role of an organic bromide salt in electrocatalysis》, the research content is summarized as follows. An electrochem. transformation was represented by demonstrating the dual role of an organic bromide salt, i.e., tetra-n-butylammonium bromide (TBAB), as a brominating agent and as an electrolyte for the regioselective bromination of several imidazo heteroaromatic motifs, e.g., I. Instead of using a transition metal/external oxidant, this methodol. utilized electron holes and electrons by means of anodic oxidation and cathodic reduction to form the desired products in good to excellent yields at ambient temperature The method was simple, environment friendly and compatible with various functional groups. The significance of this sustainable greener bromination technique relies on the fact that the readily available cost-effective electrodes (C(+)/C(-)) could be reused up to forty times without loss of any electrochem. activities. The electro-oxidative method could efficiently be scaled up and can be extended to chlorination as well. Moreover, this electro-synthetic strategy was extrapolated to the domino organo-electrochem. bromination technique for the synthesis of a brominated imidazo heteroaromatic moiety directly starting from substituted 2-bromoacetophenone and 2-aminopyridine by using catalytic amounts of electrolyte.

Pu, Yunchuan;Yang, Ziqi;Wee, Vanessa;Wu, Zhongjie;Jiang, Zhongyi;Zhao, Dan research published 《 Amino-functionalized NUS-8 nanosheets as fillers in PIM-1 mixed matrix membranes for CO₂ separations》, the research content is summarized as follows. Membrane-based separation technologies are promising for various applications such as carbon capture and storage (CCS). Herein, we report the preparation and performance of mixed matrix membranes (MMMs) for carbon dioxide (CO₂) separation The MMMs comprise amino-functionalized metal-organic framework (MOF) nanosheets (NUS-8-NH₂) dispersed in the polymer of intrinsic microporosity 1 (PIM-1). Specifically, the MOF nanosheets were synthesized through a bottom-up method and introduced into the PIM-1 matrix to fabricate NUS-8-NH₂/PIM-1 MMMs. The uniformly dispersed MOF nanosheets could afford addnl. fast transport pathways through intra-flake pores and inter-flake nano-channels. Moreover, the amino groups could enhance CO₂ transport within NUS-8-NH₂/PIM-1 MMMs. In addition, hydrogen bonding between the NUS-8-NH₂ filler and PIM-1 matrix improved interfacial compatibility. Therefore, the as-prepared MMMs could achieve a high filler loading of 15 wt% without sacrificing separation performance. Compared with the pure PIM-1 membrane, the MMM with 10 wt% NUS-8-NH₂ showed CO₂ permeability of ∼14000 Barrer and a CO₂/N₂ selectivity of ∼30, surpassing the 2008 Robeson’s upper bound.

Qiu, Boya;Alberto, Monica;Mohsenpour, Sajjad;Foster, Andrew B.;Ding, Shengzhe;Guo, Zunmin;Xu, Shaojun;Holmes, Stuart M.;Budd, Peter M.;Fan, Xiaolei;Gorgojo, Patricia research published 《 Thin film nanocomposite membranes of PIM-1 and graphene oxide/ZIF-8 nanohybrids for organophilic pervaporation》, the research content is summarized as follows. In this work, thin film nanocomposite (TFN) membranes of super-glassy polymer PIM-1 containing zeolitic imidazolate framework-8 (ZIF-8)/graphene oxide (GO) composites (ZG) have been prepared by dip-coating onto water pre-impregnated polyvinylidene fluoride (PVDF) substrates. Higher flux and improved separation factors as compared to bare PIM-1 thin film composite (TFC) membranes have been achieved in organophilic pervaporation; for an aqueous feed solution with 5 wt% of butanol at 65°C, a total permeate flux of 7.9 ± 0.69 kg m-²h^-1 and a separation factor (β_BtOH/H2O) of 29.9 ± 1.99 have been obtained with a TFC membrane containing 0.5 wt% of ZG filler. The pervaporation separation index (PSI) of this membrane (228 kg m^-2h^-1) is amongst the highest values reported in the literature. This excellent performance is attributed to the formation of a defect-free PIM-1 active layer (<1μm) and the hydrophobic nature of the ZG fillers.

Quintavalla, Arianna;Veronesi, Ruben;Speziali, Laura;Martinelli, Ada;Zaccheroni, Nelsi;Mummolo, Liviana;Lombardo, Marco research published 《 Allenamides Playing Domino: A Redox-Neutral Photocatalytic Synthesis of Functionalized 2-Aminofurans》, the research content is summarized as follows. A photoredox catalytic synthesis of functionalized 2-aminofurans I [R = OPh, 2-oxooxazolidin-3-yl, indol-1-yl, etc.; R¹ = Me, Ph, 2-thienyl, etc.; R² = H, Me, CO₂Et, etc.] was proposed starting from α-halo carbonyl substrates and N-allenamides. The use of visible light as green energy source, redox-neutral nature of the transformation allowing to avoid additives and strong oxidants, mild reaction conditions and the functional groups tolerance, low photocatalyst loading and the absence of excess reagents, one-pot formation of three new bonds in a domino sequence, these features of this protocol made it particularly efficient and sustainable. According to mechanistic hypothesis, the transformation was configured as a double radical-polar crossover reaction, in which the photocatalyst was excited, oxidized and reduced twice for each mol. of 2-aminofuran produced. The novelty of the designed synthetic approach also lied in the use of N-allenamides as substrates, which, after the addition of the first electrophilic radical, preserve a further reactive π-system, made possible the addition of a second α-keto radical and enabling the installation of a keto functionality at a remote position. The good yields, broad scope and possibility to further synthetically elaborate the obtained furans made this protocol particularly promising for the construction of useful products.
