A NEW HALIDE-FREE ROUTE TO METALLOORGANIC CADMIUM COMPLEXES - SYNTHESES AND STRUCTURAL CHARACTERIZATIONS OF [CD(PHCC)(2)(TMEDA)] AND [CD(C12H8N)(4)](2-).2LI(THF)(4)+ (TMEDA=ME(2)NCH(2)CH(2)NME(2))

The syntheses of the monomeric diorganocadmium complex [Cd(PhC=C)(2)(tmeda)] 1, the first structurally characterised Cd-acetylide, and of the ion-separated [Cd(C12H8N)(4)](2)-.2Li(thf)(4)(+) 2, containing a metallo-organic Cd dianion, from the nucleophilic substitution reactions of Cd(NSiMe(3))(2) with PhC=CLi (1:1 or 1:2 equiv.) and with C12H18NLi(1:1-4 equiv.) respectively, exemplify a new, halide-free and general route to metallo-organic complexes.
