Bisdisubstituierte aromatische Phosphane als Komplexliganden / Bisdisubstituted Aromatic Phosphanes as Ligands for Metal Complexes

Abstract

The photochemical reaction of o-C6H4(PR2)2; R = OCH3, OC2H5 , m-C6H4(PR2)2; R = N(CH3): and p-C6H4(PR2)2; R = OCH3. N(CH3)2 with (tricarbonylj(methylcyclopentadienyl)- manganese (Cp')Mn(CO)3 (6) and p-C6H4(P(N(CHO3)2)2)2 with (tricarbonyl)(methyl)(cyclopenta- dienyl)molybdenum (CH3)(Cp)Mo(CO)3 (7) yields new manganese and molybdenum complexes. o-Phenylen-bis(phosphonousaciddimethylester)(carbonyl)(methylcyclopentadienyl )manganese (8) forms yellow crystals, whose structure is reported. The reaction of o-C6H4(P(OCH3)2)2 (1) with NiCl2 gives a 1:1 phosphane complex (14). Ni(OH)Clopm. The complexes are characterized by elemental analysis, 1H NMR, 31P NMR, IR and mass spectroscopy.
