Synthesis and Reactivity of Palladium Complexes Bearing Phosphino-Amidinate Ligands: O–H Bond Activation by Metal–Ligand Cooperation

Phosphine ligands bearing amidine groups were designed for the synthesis of complexes in which a metal center and ligands cooperate. Several palladium amidinate complexes were synthesized from these ligands. The reaction of these complexes with various organic molecules containing an acidic OH group gave the palladium amidine complexes. In the reaction, the O–H bond was activated by metal–ligand cooperation (MLC).
