DOI:10.1039/c9cc03591e
日期:——
dehydrogenative coupling is presented. A simple nickel catalyst system stabilised by readily available nitrogen ligands enables a series of interesting E-configured vinylarenes (confirmed by X-ray crystal-structureanalysis) to be synthesised in good to excellent yields with olefin/alkane selectivity of >20 : 1. Hydrogen and water are generated as byproducts and quantitative determination of H2 was performed

Herein, we present the first catalyticdirectolefination of methyl‐substituted heteroarenes with primary alcohols through an acceptorless dehydrogenative coupling. The reaction is catalyzed by a complex of the earth‐abundant transition metal manganese that is stabilized by a bench‐stable NNN pincer ligand derived from 2‐hydrazinylpyridine. The reaction is environmentally benign, producing only hydrogen
