Abstract

A general and mostly highly stereoselective method for effective synthesis of 1-boryl-3-(silyl)propenes via one-step ­catalytic processes, i.e. silylative coupling of vinylsilanes with allyl boronates, borylative coupling of vinyl boronates with allylsilanes catalysed by [RuHCl(CO)(PCy3)2] and cross-metathesis of respective derivatives in the presence of Grubbs catalysts, is described.
