The catalytic system PdCI,(PPh,),-HCI is highly active and selective in the hydrogen transfer reaction from H,O-CO to PhCOCH,CHOHCOOH which yields the corresponding y-keto acid PhCOCH,CH,COOH, with concomitant evolution of C02. An increase of temperature, pressure of carbon monoxide and catalyst con
