Palladium-catalysed three-component coupling reactions of dimethylsilacyclobutane, carbon monoxide and organic halides: a convenient route to cyclic silyl enol ethers
Abstract
A facile one pot synthesis of cyclic silyl enol ethers, 1-sila-2-oxacyclohex-3-enes has been achieved by coupling reactions of strained 1,1-dimethyl-1-silacyclobutane with organic halides in CO atmosphere (1 atm) in the presence of palladium catalysts.
