Abstract

Reaction of diarylmethylenetriphenylphosphoranes with sulfur gave thiobenzophenones and triphenylphosphine sulfide in good yields. Reaction of benzylidenetriphenylphosphoranes with sulfur gave triphenylphosphine sulfide and 5, 7- diphenyl-l, 2, 3, 4, 6-pentathiepane. More active alkylidenetriphenylphosphoranes such as isopropylidene-or sec-butylidenetriphenylphosphorane gave the corresponding ...
