T. Ohmura et al., A STEREOSELECTIVE ISOMERIZATION OF ALLYL SILYL ETHERS TO (E)-SILYL OR(Z)-SILYL ENOL ETHERS USING CATIONIC IRIDIUM COMPLEXES, Chemical communications, (13), 1998, pp. 1337-1338
A cationic iridium complex, prepared via the hydrogenation of [Ir(cod)
(2)]PF6-2PPr(3) is found to be an excellent catalyst for the stereosel
ective isomerization of primary allyl silyl ethers to (E)-enol ethers
and secondary allyl ethers to (Z)-enol ethers.
