Synthesis of Pd catalysts based on a nonbornene - CO copolymer and their properties in the carbomethoxylation of propylene

Article abstract of DOI:10.1007/BF02498969

It was found that carboxylation of norbornene (nbn) in the presence of the PdCl₂ -PPh₃ - HCl catalytic system is accompanied by alternating copolymerization of nbn with carbon monoxide to form norbornanecarboxylic acid (yield -20%) and a nbn-CO copolymer (yield -80%, M_w = 1600, M_w/M_n = 1.6). The Pd^II salt of poly(norbornaneketone)carboxylic acid is a highly active catalyst for the carbomethoxylation of propylene.
