Synthesis and characterization of palladium amido complexes containing pincer CNO ligands through nitrene insertion: Pincer palladium amido complexes

Catellani reactions of aryl iodides allow the double functionalization at the ortho and ipso positions in one pot. Catellani reactions involving a nitrene intermediate are not yet known. In this paper, a few palladium amino complexes were prepared from PdCl2, anthranil and iodoarenes, and their structures were determined by X-ray single-crystal diffraction. These complexes are supported by a pincer C,N,O tridentate ligand forming fused six-membered palladacycles. The high stability of the palladium complexes inhibits their reductive elimination.
