Novel coordination of a neutral borane adduct to nickel(0). Formation of Ni(CO)/sub 2/(B/sub 2/H/sub 4/. 2P(CH/sub 3/)/sub 3/)
The synthesis and characterization of Zn(II) and Cu(I) complexes of bis(trimethylphosphine)-di-borane(4), B/sub 2/H/sub 4/.2P(CH/sub 3/)/sub 3/ was reported. These compounds represented the first examples of metal complexes of a neutral borane adduct and featured coordination of the boron hydride ligand to the metal via two B-H-M bridges. This bidentate-bridging mode of coordination had previously been observed primarily in complexes of the B/sub 2/H/sub 4//sup -2/, B/sub 2/H/sub 6//sup 2 -3/ /sup 4/ and B/sub 3/H/sub 8//sup -5/ /sup 6/ borane anions. Of these complexes of the anions, only a few are known to have the metal center in oxidation state zero. So far there have not been reports of these anions complexing to the Ni(O) center. This work reports that the neutral borane adduct B/sub 2/H/sub 4/.2P(CH/sub 3/)/sub 3/ will react with Ni(CO)/sub 4/ to form a stable, isolable Ni(O) complex, Ni(CO)/sub 2/-(B/sub 2/H/sub 4/.2P(CH/sub 3/)/sub 3/), which contains two B-H-M bridge bonds to the Ni(O) center. The new nickel complex was formed by the direct reaction of Ni(CO)/sub 4/ and B/sub 2/H/sub 4/.2P(CH/sub 3/)/sub 3/ in dichloromethane at room temperature. 7 references, 1 figure.
