Synthesis and coordination chemistry of the new unsymmetrical ligand Ph2PCH2NHC6H4PPh2

Condensation of Ph2PCH2OH with 2-(diphenylphosphanyl)-aniline in toluene gave the new unsymmetrical ligand Ph2PCH2NHC6H4PPh2 (1) in good yield. Oxidation of 1 with H2O2 or elemental sulfur led to the oxidised products Ph2P(O)CH2NHC6H4P(O) Ph2 (2) and Ph2P(S)CH2NHC6H4P(S) Ph2 (3). The new ligand 1 demonstrates three distinct modes of coordination. Reaction of compound 1 with [MX2(cod)] (M = Pd, Pt; X = Cl, Br, Me) or [Mo(CO)4(pip)2] gave the chelate complexes [PdCl2(Ph2PCH2NHC6 H4PPh2-PX,PA)] (4), [PdBr2(Ph2PCH2NHC6 H4PPh2-PX,PA)] (5), [PtCl2(Ph2PCH2NHC6 H4PPh2-PX,PA)] (6), [PtMe2(Ph2PCH2NHC6 H4PPh2-PX,PA)] (7) and [Mo(CO)4(Ph2PCH2NHC6 H4PPh2-PX,PA)] (8). Coordination of 1 with [{RuCl(μCl)(η3:η3-C10 H16)}2] or [{RhCl(μ-Cl)(η5-C5Me5)}2] gave the monodentate complexes [RuCl2(η3:η3-C10 H16)(Ph2PCH2NHC6 H4PPh2-PX)] (9) and [RhCl2(η5-C5Me5) (Ph2PCH2NHC6H4 PPh2-PX)] (10). Reaction of 1 with [{IrCl(μ-Cl)(η5C5Me5)}2] led to a mixture from which the monodentate complex [IrCl2(η5-C5Me5) (Ph2PCH2NHC6H4 PPh2-PX)] (11) and the chelate cationic complex [IrCl(η5-C5Me5) (Ph2PCH2NHC6H4 PPh2-PX,PA)][Cl] (12) were separated. Abstraction of the chloride ligands from complexes 9 and 10 with AgClO4 gave the cationic chelate complexes [RuCl(η3:η3-C10H16) (Ph2PCH2NHC6H4 PPh2-PX,PA)][ClO4] (13) and [RhCl(η5-C5Me5)(Ph2 PCH2NHC6H4PPh2-PX, PA][ClO4] (14). Compound 1 also functions as a bridging ligand when reacted with two molar equivalents of [AuCl(tht)] or one molar equivalent of [{RhCl(μ-Cl)(η5-C5Me5)}2] to give the bimetallic complexes [Ph2P{AuCl}CH2NHC6H4 PPh2{AuCl}] (15) and [{RhCl2(η5-C5 Me5)}2(Ph2PCH2NHC6 H4PPh2)] (16). The dioxidised compounds 2 and 3 and several typical complexes 8, 9, 11 and 14 were structurally characterised by X-ray diffraction. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
