摘要

The stereoselective isomerization of unsymmetrical diallyl ethers to allyl(E)-vinyl ethers was carried out in the presence of a cationic iridium(I) catalyst.The catalyst prepared in situ by treating [Ir(cod)(PPh_2Me)_2]PF_6 with hydrogen was found to be an excellent catalyst to selectively isomerize the less substituted allyl group to an (E)-vinyl ether.
