Abstract

A Series of rhodium (III) cyclometallated complexes of the type (RhHCl(NC5H2C=N Ar (PPh3)2} (Ar=Substituted aryl), have been synthesized and characterized. Schiff bases derived from a substituted benzaldehyde and 2-amino pyridine substituents were allowed to react with [RhCl(PPh3)3] or [Rh(μ-Cl)(COD)]2 in the presence of 4 equivalents of PPh3 (or Ph2BzP) to give Rh(III) Cyclometallated complexes, in which the imine C-H bond was added oxidatively to the rhodium metal to give (H-M-C). The complexes were characterized using IR and NMR spectroscopy confirmed by elemental micro-analysis. The absorption of the hydride ligand was inferred as trans to N-donar ligand.
