The oxidation of the complexes W(CHPh)(X)(BHPz3)(Br) (X = NCMe3, N-1-adamantyl, NC6H2-2,4,6-(CH3)3, O) with Br2 was investigated. The net outcome of the reactions is insertion of the benzylidyne unit into one of the W-N bonds of the tungsten tris(pyrazolyl)borate cage to afford the complexes W{[C(Ph)-C3H3N2-BHPz2)](X)(Br2). The crystal structures of two compounds of this type of complex with X = N-1-adamantyl and X = O have been determined by X-ray crystallography. (C) 2000 Elsevier Science S.A.

The regioselective addition of Pt-H or Pt-R (R = Me, CH=CH2) bonds across the M-C triple bonds of alkylidyne ligands affords cationic heterodinuclear complexes containing μ-alkylidene ligands in one step. The syntheses of five alkylidyne and seven η-alkylidene compounds are reported. Addition of a Pt-H+ reagent to a (diethylamino)alkylidyne complex gives a μ-η1,η2-(diethylamino)methylidene ligand which is described best as a bridging σ,π-(diethyliminium)methyl ligand. The X-ray structure of this complex is reported: {PtW[μ-η1,η2-C(H)(NEt2)](HBpz 3)(CO)2(PEt3)2}BF4; monoclinic; P21; Z = 2; a = 10.991 (5) A?, b = 13.956 (4) A?, c = 13.684 (4) A?; β = 95.05 (3)°.
