Abstract: Herein, we describe a photocatalytic strategy for decyanative hydrofunctionalization of styrenes with α-heteroatom-substituted acetonitriles. This strategy facilitates the generation of α-heteroatom methyl radicals from acetonitriles through cyano group transfer (CGT) enabled by amine-ligated boryl radicals.… read more here.

DOI: 10.1021/jacs.5c12677
Abstract: The [2 + 1] cycloaddition of carbenes with alkenes is widely regarded as one of the most straightforward strategies for synthesizing cyclopropanes, which are ubiquitous motifs in pharmaceuticals. A significant challenge in cyclopropanation reactions is… read more here.
