A stereoselective isomerization of allyl silyl ethers to (E)- or (Z)-silyl enol ethers using cationic iridium complexes

Abstract

A cationic iridium complex, prepared via the hydrogenation of [Ir(cod)₂]PF₆–2PPr₃ is found to be an excellent catalyst for the stereoselective isomerization of primary allyl silyl ethers to (E)-enol ethers and secondary allyl ethers to (Z)-enol ethers.
