Reaction of N-ligated methylpalladium(II) alkoxide and aryloxide complexes [Pd(Me)(OR)(N ∼ N)] (R = Ph, CH(CF3)2; N ∼ N tmeda (N,N,N′,N′-tetramethylethylenediamine) or bpy (2,2′-bipyridyl)) with carbon monoxide produces the corresponding methylesters in high yields. The insertion takes place either into the PdMe bond (aryloxide complexes) or into the PdOR bond (alkoxide complexes). Methylalladium(II)

formed together with small amounts of the insertion product, MeC(O)C⋮CPh (3%). Crystals of [Pd(Me)(OC6H5)(PCN)]·CH2Cl2 and its adduct with HOC6H5 have been subjected to X-ray diffraction studies. The molecular structure of the latter adduct shows an OH···O hydrogen bond between the phenol and the oxygen atom of the phenoxide unit.
