Use of the complex (Cy3P)2NiCl2 rather than [Rh(dppe)]ClO4 as catalyst facilitates regioselective preparation of lithiumenolates via isomerization of the corresponding allylic alkoxides. The nickelcatalyst also succeeds in isomerizing certain di- and trisubstituted allylic alkoxides that are inert to the rhodium system.

Highly efficient isomerization of allylicalcohols into saturated carbonyls is accomplished using the catalyst system of Cp*RuCl[Ph2P(CH2)2NH2-kappa2-P,N]-KOt-Bu (Cp* = eta5-C5(CH3)5) under mild conditions. Mechanistic consideration based on isotope-labeling experiments indicated the present reaction is applicable to the asymmetricisomerization of racemic sec-allylic alcohols with a prochiral olefin
