Both phosphorus and nitrogen containing ligands have been used to synthesize a variety of metal complexes. The mixed phosphorus-nitrogen ligands can often be viewed as a phosphorus ligand with the possibility for pendant nitrogen coordination. Some new mixed P,N ligands have been synthesized from cyclohexylphosphine, formaldehyde and aniline. Both a pendant nitrogen compound, CyP(CH2NPh)2 (where Cy = C6H11 and Ph = C6H5), and a heterocyclic six membered ring compound, 5-cyclohexyl-1,3-diphenyl-1,3,5-diazaphosphinane, have been characterized. X-ray structural analysis of the phosphinane ligand shows a cyclohexane-like structure with equatorial cyclohexyl and phenyl groups.
