The Pd phosphine complex with fullerene C-60 (eta(2)-C-60 Pd(PPh3)(2))
(I) is used as the catalyst for homogeneous and heterogeneous hydroge
nation of 3,7-dimethylocta-6-en-1-yn-3-ol (dehydrolinalool) (DHL). In
all cases, the triple bond of DHL is hydrogenated into the double bond
in the presence of the palladium-fullerene complex. The sibunit-suppo
rted complex I exhibits the highest catalytic activity, which is by an
order of magnitude higher than that of the Pd-sibunit catalyst.
