Tin-free Radical Cyanation of Alkyl Iodides and Alkyl Phenyl Tellurides

Abstract

As a result of much faster phenyl telluride group transfer relative to the corresponding iodine atom transfer, tin-free radical cyanation of alkyl phenyl tellurides has been achieved with p-toluenesufonyl cyanide and methyl allyl sulfone in the presence of V-40 as initiator.
