To date, a plethora of λ3-P nitrogen-containing compounds is known. A large number of them are used as ligands in coordination chemistry and homogeneous catalysis. PN-containing compounds tend to build up cyclic moieties, which have received less attention in regard to their application as ligands in transition metal chemistry. Hence, different dehalogenation reactions of N,N-bis{chloro(aryl)-phosphino}-amines have been developed to synthesize different P-N-P containing cyclic compounds. Their coordination behavior to group VI transition metal carbonyls was explored.

The ligand (MeNPMe)4 (L) forms complexes (L.CoCl+)2CoCl42-, (L.CoCl)+BPh4-, L.M(CO)3 (M= Cr,Mo,W,Mn+), and a nickel complex L.Ni2(CO)3, which is easily oxidised to the phosphonimide 4.Quaternary complexes +I- have been prepared both by quaternisation of the neutral complex (R = Me, CH2CN, CH2C(O)NH2, M = Cr, Mo, W) and (R = Me) by reaction of the simple quaternary with the metal carbonyl.The quaternary complexes have been deprotonated to ylidic complexes, L.M(CO)3CH2 (M = Mo, W) in which the ylidic group has displaced one phosphine function.Chemical and structural features are discussed in terms of d-orbital contraction by acceptor groups.The phosphazane (MeNPPh)4 has been prepared.
