Alkylation and arylation of 2-trimethylsiloxyallyl halides. A new regiospecific route to silyl enol ethers☆

Abstract Alkylation and arylation of 2-trimethylsiloxyallyl halides with lithium dialkyl- and diarylcuprate, respectively, gave silyl enol ethers in a regiospecific manner.

Novel and facile syntheses of t-butyl substituted silanes from t-butyl magnesium chloride and chlorosilanes catalyzed by cuprous cyanide

Abstract t-Butyl substituted silanes, e.g. t-butyldimethylchlorosirane, were successfully obtained by cuprous chloride promoted coupling reaction of t-butyl Grignard reagent and chlorosilanes.

α-Carboxylation reaction of carbonyl compounds with bromomagnesium ureide-carbon dioxide adducts

Abstract Bromomagnesium ureide-carbon dioxide adducts, models of the carboxylated biotin complex, undergo caboxylation of a variety of carbonyl compounds in good yield.
