Dilithium cyanocuprates R\*LCu(CN)Li2 (L=2-Th, Me) react with vinylic tellurides of Z configuration, RCH=CHTeRl to give higher order vinylic cyanocuprates, [(RCH=CH)LCu(CN)Li2]. By changing the gegenion from lithium to magnesium [R2LCu(CN)LiMgBr or R2LCu(CN)(MgBr)2] the reaction gives cross -couplin
