Conclusions 1.1-Hexen-5-one in the presence of the triphenylphosphine complexes of Ru and Rh, in a H2 atmosphere, at 82°, is isomerized to give cis- and trans-2-hexen-5-one, and is reduced to 2-hexanone.2.RuCl2(PPh3)3 catalyzes mainly the shift, while RhCl(PPh3)3 catalyzes mainly the reduction of the C=C bond of 1-hexen-5-one. The reduction is accomplished mainly via the transfer of hydrogen from a secondary alcohol.3.The carbonyl group of 1-hexen-5-one is not reduced due to the predominant coordination of the unsaturated ketone via the C=C bond, and not via the C=O group. |
