COMPLEXES OF PdCl2 WITH PHOSPHORYL- AND THIOPHOSPHORYL-SUBSTITUTED PHOSPHINES AS CATALYSTS FOR THE HYDROCARBOXYLATION OF OLEFINS

Article abstract of DOI:10.1007/BF00863571

The influence of the ligands Ph2P(CH2)mP(X)Ph2(L), where m = 1, 2 and X = O, S, on the rate and regional selectivity of the hydrocarboxylation of α-olefins has been investigated, catalyzed by PdCl2, in a series of organic solvents.A high regional selectivity of the process (>80percent) for products with normal structure has been achieved by using L with m = 2, X = O.The influence of the ligand used and of triphenylphosphine on the properties of the catalytic system in the given reaction has been compared. Keywords: hydrocarboxylation, palladium chloride complexes, bidentate diphosphines, catalysis.
