Abstract
Isomerization of allylic and homoallylic alcohols is catalyzed by the zwitterionic Rh(I) complex (sulphos)Rh(cod) in water-n-octane to give the corresponding aldehyde or ketone in high yields and chemoselectivity. A metal hydride mechanism is proposed on the basis of various independent experiments in both homogeneous and biphasic systems [sulphos=-O3S(C6H4)CH2C(CH2PPh2)3File in questo prodotto:
