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

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.
