ABSTRACT:
This invention relates to sulfido(disulfido)bis(N,N-substituted dithiocarbamato)W(VI) complexes, their preparation and use. More particularly, this invention relates to compounds of the formula WS(S.sub.2) (S.sub.2 CNR.sub.2).sub.2 which are mononuclear, seven-coordinate, neutral W(VI) complexes containing only seven sulfur atoms in the Mo coordination sphere. R is hydrogen, an alkyl, aryl, cycloalkyl group or mixture thereof. Preferably all of the R's are the same and are alkyl groups. These compounds are useful as catalysts or catalyst precursors for removing sulfur from sulfur containing hydrocarbons.
