Preparation of Hybrid Bidentate Phosphine Ligands by Reduction of Their Benzyl- or Phenyl-phosphonium Salts. X-Ray Crystal Structure of 2-Aminophenyltriphenylphosphonium Tetrachloronickelate(II)

The 2-substituted phenylphosphine bidentate hybrid ligands, 2-aminophenyl-, 2-methylaminophenyl-, 2-hydroxyphenyl- and (2-amino-3-methylphenyl)-diphenylphosphine, (1a-d), respectively, and 2-aminophenylmethylphenylphosphine, (1e), were synthesized by reduction of their phenylphosphonium halides, (2a-e)X (X = Cl or Br), with sodium naphthalenide in tetrahydrofuran at -68 deg, or electrochemically at a mercury cathode.The phosphonium salts were prepared by reaction of triphenylphosphine with aryl halide and anhydrous nickel halide at 200 deg.X-Ray diffraction of (2a)2 showed it to have monoclinic space group P21/n, a 10.657(4), b 20.966(3), c 20.422(6) Angstroem, β 101.33(2) deg and Z 4.The structure was refined by a full-matrix least-squares procedure to a final R 0.050 for 3534 reflections with I > 2.5?(I).
