ABSTRACT:
This invention provides a process to regioselectively silylcarbonylate 1-alkynes and in predominantly the Z-isomer with substantial absence of hydrosilylation by-products. The process involves reacting a 1-alkyne with an organosilane and carbon monoxide in a solvent in the presence of a catalyst. The catalyst is a carboxylate salt of a metal such as rhodium, iridium or rhenium.
