Carboxymethylation of Organic Halides by Palladium Complexes under Mild Conditions

Abstract

Abstract Palladium complexes, Pd(CO)(PPh3)3, Pd3(CO)3(PPh3)4, Pd3(CO)3(PPh3)3, and PdCl2(PPh3)2 were found to be excellent catalysts for the carboxymethylation of various organic halides under very mild conditions. The carboxymethylation reaction is considered to proceed via acyl complexes as the intermediates.
