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.
