Chemoselective Hydrogenation of Nitroarenes Using an Air-Stable Base-Metal Catalyst

Organic Letters, Journal Year: 2021, Volume and Issue: 23(7), P. 2742 - 2747

Published: March 23, 2021

The reduction of nitroarenes to anilines as well azobenzenes hydrazobenzenes using a single base-metal catalyst is reported. hydrogenation reactions are performed with an air-and moisture-stable manganese and proceed under relatively mild reaction conditions. transformation tolerates broad range functional groups, affording aniline derivatives in high yields. Mechanistic studies suggest that the proceeds via bifunctional activation involving metal–ligand cooperative catalysis.

Dual-ionic imidazolium salts to promote synthesis of cyclic carbonates at atmospheric pressure

Green Energy & Environment, Journal Year: 2021, Volume and Issue: 7(6), P. 1327 - 1339

Published: Feb. 25, 2021

Novel dual-ionic imidazolium salts are shown to display excellent catalytic activity for cycloaddition of carbon dioxide and epoxides under room temperature atmospheric pressure (0.1 MPa) without any solvent co-catalyst leading 96.1% product yield. It can be reused five times keep the yield over 90%. These intriguing results attributed a new reaction mechanism, which is supported by theoretical calculations along with measurements 13C NMR spectrum Fourier transform infrared spectroscopy (FT-IR). The traced CO2-philic group an electrophilic hydrogen atom. Our work shows that incorporation feasible pathway develop efficient ionic liquids.
