  Synthesis and nuclear magnetic resonance solution studies of zerovalent nickel-carbonyl-dppm complexes

  摘要：

  Three nickel-carbonyl-dppm complexes, Ni(CO)2(eta1-dppm)2, Ni2(mu-dppm)2(mu-CO)(CO)2 and Ni2(mu-dppM)2(CO)4 have been prepared by minor modifications of a single synthetic procedure. The complexes were characterized in the solid state by IR analysis and in solution by P-31 NMR analysis. In solution, at 25-degrees-C, Ni(CO)2(eta1-dppm)2 rearranges to initially form Ni2(mu-dppm)2(mu-CO)(CO)2, CO and dppm followed by the subsequent reaction of Ni2(mu-dppm)2(mu-CO)(CO)2 With CO to yield Ni2(mu-dppm)2(CO)4. Carbon monoxide gas uptake measurements were conducted to determine the extents of the interconversions of the three nickel-carbonyl-dppm complexes at 25-degrees-C and 700 torr. Reaction of CO with Ni(CO)2(eta1-dppm)2 yielded a fourth zerovalent complex, Ni(CO)3(eta1-dppm).

  Syntheses of the d(10)-d(10) ionic complexes [NiCu(CO)(2)(mu-dppm)(2)(MeCN)(2)]X (dppm = Ph(2)PCH(2)PPh(2), X = ClO4, BPh(4) or PF6), containing four-coordinate copper, and the related complex NiCu(CO)(2)(mu-dppm)(2) (BH3CN) from reactions of Ni(CO)(2)(eta(1)-dppm)(2) with copper(I) species are reported as is the crystal structure of the second of these compounds. This shows a tetrahedral arrangement about nickel(0), a slightly distorted trigonal planar arrangement about copper(I), a Ni-Cu distance [3.171(4) Angstrom] which is too great for significant metal-metal interaction, and a cradle type of arrangement for the Ni-Cu-dppm framework in the solid state. Attempts to prepare related d(10)-d(10) Ni(0)-M(I or II) (M = Ag, Au, Zn or Hg) complexes by similar methods were not successful but a Ni-Au complex of limited stability can be identified in related reactions involving Ni-2(mu-CO)(CO)(2)(mu-dppm)(2).
