Abstract

Dilithium cyanocuprates R(2)LCu(CN)Li-2 (L=2-Th, Me) react with vinylic tellurides of Z configuration, RCH=CHTeR(1) to give higher order vinylic cyanocuprates, [(RCH=CH)LCu(CN)Li-2]. By changing the gegenion from lithium to magnesium [R(2)LCu(CN)LiMgBr or R(2)LCu(CN)(MgBr)(2)] the reaction gives cross-coupling products of Z configuration, RCH=CHR(2) in good yields.
