The catalytic activities of palladium complexes containing phosphorus-nitrogen ligands is reported. The catalysts studied showed high activities in the aminocarbonylation of aryl iodides. The palladium complexes reported activities between 100% and 58% in the aminocarbonylation reaction. The reactions are very selective for the double carbonylative amination of aryl halides. The major product is N,N-diethyl-α-oxo benzeneacetamide (96/4). The reaction was made under mild conditions of temperature and carbon monoxide pressure.

Organized crystal packing from non-covalent dimers and the self-dimerization in solution of Cu(NN′)(PPh3)Br] were characterized. Differences in Cu(ii)/Cu(i) potentials between the monomer and dimer are modulated by the non-covalent interactions.
