Synthesis and Reactivity of 2-Aminophenylpalladium(II) Complexes: Insertion Reactions of Oxygen and Carbon Monoxide into Carbon−Palladium Bonds—New Examples of “Transphobia”

Insertion of CO into 2-aminophenylpalladium complexes leads to 2-aminobenzoylpalladium derivatives. When these compounds are forced to coordinate a carbon donor and a phosphane ligand in the trans position, a C−P coupling process or an insertion of oxygen occurs (see scheme). In this case, a dinuclear palladium complex containing a bridging anthranilato ligand is isolated.
