Abstract

The hydrochlorides of cysteamine, cysteine ethyl ester and penicillamine methyl ester, react with Pd(PPh3)4 to yield low symmetry complexes of palladium(II) that incorporate the N,S-aminothiolato ligand and triphenylphosphine; the complex with cysteine ethyl ester, structurally characterized by X-ray diffraction, proved to be an effective catalyst for the hydrocarboxylation of styrene with high selectivity (98%) towards 2-phenylpropanoic acid.
