Two series of novel tetrahedral copper(I) complexes comprising tridentate PNP-aminodiphosphines and tetradentate PN(X)P-substituted aminodiphosphines (X = O, S) have been prepared and characterized by conventional physico-chemical techniques. The first series includes ‘3 + 1’-type complexes comprising an aromatic PNP-aminodiphosphine and acetonitrile or triphenylphosphine. In the second series, the central amine function of the PNP-ligand was substituted with functionalized pendant arms containing ether, hydroxyl or thioether groups to enhance the chelation ability of the ligand.

Abstract

Two series of novel tetrahedral copper(I) complexes comprising tridentate PNP-aminodiphosphines and tetradentate PN(X)P-substituted aminodiphosphines (X = O, S) have been prepared and characterized by conventional physico-chemical techniques. The first series includes ‘3 + 1’-type complexes comprising an aromatic PNP-aminodiphosphine and acetonitrile or triphenylphosphine. In the second series, the central amine function of the PNP-ligand was substituted with functionalized pendant arms containing ether, hydroxyl or thioether groups to enhance the chelation ability of the ligand. Fully coordinated neutral and cationic complexes were isolated. A preliminary study investigating both the labelling of 64Cu with the prototype PN(S)P ligand and the potential cytotoxic activity of the ‘cold’ [Cu(PN(S)P)][BF4] complex is reported.
