Synthesis and reactivity of Rh and Ir imino and azidophosphonamido complexes

Abstract

This work reports a family of iminophosphonamido Rh and Ir cyclooctadiene (COD) complexes, [Ph2P(NR)2]M(COD), where the substituents on nitrogen vary, R = 2,4,6-trimethylphenyl (Mes) or adamantyl (Ad). The reaction chemistry of the iminophosphonamido Rh and Ir COD complexes was probed. This work also demonstrates the synthetic route to and of a family of azidophosphonamide Rh and Ir phosphazide containing ligand cyclooctadiene (COD) complexes, [Ph2P(N3R)(NR])M(COD). The unusual ligand linkage isomerism of said species is discussed. Preliminary results pertaining to bis(cyclooctene) (COE) complexes bearing both ligand types are also reported.
