摘要:
Organic compounds are hydrogenated in the presence of certain bis(pentadienyl) divalent Group IV metal complexes having &pgr;-bound, neutral, conjugated diene ligands. These complexes are effective hydrogenation catalysts for polymers containing ethylenic unsaturation. They further provide for selective hydrogenation of ethylenic unsaturation sites in the presence of aromatic groups.
