Full title: Phosphoranimine phosphines and arsines as heterodifunctional coordinating ligands. Synthesis and characterization of new palladium(II) metallacycles RN=PPh2(CH2)nEPh2PdCl2 (R = SiMe3, GeMe3, H; n = 1, 2; E = P, As) and the crystal and molecular structure of HN=PPh2CH2PPh2PdCl2, the first structural example of a phosphoranimine phosphine complex. Reaction of the N-(trimethylsilyl)- or N-(trimethylgermyl)phosphoranimine phosphines Me3ENPPh2CH2PPh2 (E = Si, Ge) or the N-(trimethylsilyl)phosphoranimine arsine Me3SiNPPh2CH2CH2AsPh2 with PdCl2(PhCN)2 gave metallacyclic PdII derivatives Me3ENPPh2(CH2)nQPh 2PdCl2 (Q = P, n = 1, E = Si or Ge; Q = As, n = 2, E = Si). Water reacts with Me3SiNPPh2CH2PPh2PdCl2 to form the parent imine complex HNPPh2CH2PPh2PdCl2 (12), the structure of which has been determined. (Crystal data for 12 (as a 1:1 adduct with CH2Cl2): monoclinic P21/n (No. 14), a = 8.953 (3) ?, b = 21.151 (4) ?, c = 14.773 (2) ?, β = 93.98 (2)°, Z = 4, final R(F) = 0.034, Rw(F) = 0.037.) The imine ligand adopts an "envelope" five-membered chelate ring configuration bonded at N and P. The Pd-N (2.021 (6) ?) and N=P (1.599 (6) ?) bond lengths are in accord with expectations for Pd-N single and P=N double bonds. The nitrogen atom is pyramidal. 12 is also formed by reaction of Me3SiNPPh2CH2PPh2 with K2PdCl4 in the presence of water. Activated fluoroaromatics (e.g. pentafluorobenzonitrile) replace Me3Si or Me3Ge groups on the ligand framework by elimination of Me3SiF and attachment of the fluoroaromatic exclusively at the para position. Full spectral characterization of all complexes is given. The Me3Ge phosphoranimine phosphine shows conformational behavior similar to that of the Me3Si analogue reported earlier. All conformers in the mixture however give a metal complex with only one conformation. We also describe a more efficient synthesis of Me3GeN3, which was developed in the course of the study.
