ABSTRACT:
An improved process for the carbonylation of aryl halides comprises contacting the aryl halide with carbon monoxide under carbonylation conditions in the presence of a co-reactant, a base, and a catalyst system formed from a source of palladium and a bidentate phosphine ligand wherein at least one monovalent phosphorus substituent is aromatic and is substituted on at least one aromatic ring carbon atom with an electron-withdrawing group.
