Metallocene sulfide chemistry of niobium and tantalum: New insights into the formation of niobium-polysulfido complexes and synthesis, structure, and reactivity of Cp{prime}{sub 2}Ta({eta}{sup 2}-S{sub 2})H (Cp{prime} = t-BuC{sub 5}H{sub 4})
- Universitaet Regensburg (Germany); and others
Permethylated Cp*{sub 2}NbS{sub 3}H (2; Cp* = C{sub 5}Me{sub 5}) and the Ta complex Cp{prime}{sub 2}TaS{sub 2}H(3) were synthesized and structurally investigated by X-ray diffraction. 2 and 3 possess M({eta}{sup 2}-S{sub 2}) cores to which either an SH (2) or a H (3) is attached. Complex 3 loses sulfur upon reaction with PR{sub 3} (R = C{sub 6}H{sub 5}, OCH{sub 3}) and CH{sub 3}I to form compounds 4 and 5, which both contain the Ta{double_bond}S moiety. 26 refs., 2 figs., 5 tabs.
