Preparation of Silyl-substituted Dizinciomethanes and Their Reactions with Electrophiles

All articles of this category Silyl-substituted bis(bromozincio)methanes (RMe 2 SiCH(ZnBr) 2 ; R = Me, Ph, and p -MeO-C 6 H 4 ), prepared from the corresponding dibromides by Pb catalyzed reaction with zinc, reacted stepwise with two different electrophiles, R 1 X and E + , yielding R 1- CH(SiMe 2 R)-E. zinc - silicon - dimetal - coupling - palladium
