✦ Synopsis

The nonionic superbase P(MeNCH 2 CH 2 ) 3 N (A) efficiently desulfurizes trisulfides to disulfides and monosulfides, disulfides to monosulfides, and propylene sulfide to propene. S‫ב‬P(MeNCH 2 CH 2 ) 3 N (B) was formed as the sulfur acceptor. P(NMe 2 ) 3 was a much poorer desulfurizing agent than A under the same reaction conditions. Thiocyanates and triphenylphosphine sulfide were also desulfurized with A, but N-(phenylthio)phthalimide formed [A-SPh] ‫ם‬ phthalimide in quantitative yield.
