Abstract
Isomerization of allylic and homoallylic alcohols is catalyzed by the zwitt erionic Rh(I) complex (sulphos)Rh(cod) in water-n-octane to give the corres ponding aldehyde or ketone in high yields and chemoselectivity. A pi -allyl metal hydride mechanism is proposed on the basis of various independent ex periments in both homogeneous and biphasic systems [ sulphos = -O3S(C6H4)CH 2C(CH2PPh2)(3)].
