摘要

The use of diphenylphosphine-terminated ethylene oligomers as ligands for palladium (0) and palladium (I1) is described. With use of these polymeric ligands, it is possible to carry out homogeneous reactions characteristic of (Ph3P) 4Pd and (Ph3P) 2Pd (OAc) 2 with essentially complete recovery of the Pd catalyst. The only limitation to repeated reuse of the catalyst is its immolative catalytic oxidation of the phosphine ligand by adventitious ...
