Abstract

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 (>80%) 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.
