Palladium(II) Complexes of Monoaryliminophosphorane Derivatives of 1,2-Bis(Diphenylphosphino)methane. Crystal Structure of [Pd{κ2-C6H3(NN−C6H4Me-4‘)-2- (C6H4Me-4‘‘)-5-C,N‘}{κ2-PPh2CH2P(NC6H4Me-4)Ph2-P,N}]

“…The reported iminophosphorane complexes can be classified into two groups depending on the number of P atoms of the ligand. Those from monophosphines are known for Mo, W, , Os, Co, ,, Rh, − Ir, ,, Ni, Pd, , Pt, , Zn, Cd, Hg, and B . With only a few exceptions, − most complexes containing iminophosphorane ligands with two phosphorus atoms are bis(diphenylphosphino)methane (dppm) derivatives.…”
