Formation of trichlorosilyl-substituted carbon-centered stable radicals through the use of π-accepting carbenes

Abstract

A radical change: Cyclic alkyl(amino) carbenes formed zwitterionic adducts with SiCl4, which were further converted into carbon-centered stable radicals by changing the donor-acceptor C→Si coordinate bond into a C-Si covalent bond through a KC8 reduction. As the carbon radical site was directly bonded to a SiCl3 unit, a radical center that is right next to an acceptor has been generated. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
