X-RAY CRYSTAL STRUCTURE OF [NI(ETA(2)-C(NBU(T))CH(SIME(3))(2))CL(PME(3))], THE FIRST STRUCTURALLY CHARACTERIZED ETA(2)-ALKANEIMIDOYL COMPLEX OF NICKEL

摘要

The alkylation of [NiCl2(PMe(3))(2)] with Mg[CH(SiMe(3))(2)]Cl yielded the alkyl dimer [Ni{CH(SiMe(3))(2)}(mu-Cl)(PMe(3))](2) (1), which readily inserted CNBu(t) to afford [Ni{eta(2)-C(NBu(t))CH(SiMe(3))(2)}Cl(PMe(3))] (4); spectroscopic and X-ray studies reveal this complex contains an eta(2)-alkaneimidoyl ligand.
