The new complexes [RuCp(PR3)(CH3CN)(2)]PF6 (R = Ph, Me, Cy) are highly acti
ve catalysts for the redox isomerization. of allyl alcohols to give the cor
responding carbonyl compounds in high yields and high efficiency. ALL react
ions proceed under mild reaction conditions. In some cases, allylations of
the carbonyl compounds could be achieved in, a tandem catalytic process.
