An "one pot" method to synthesize triphenylphosphine was found from the reduction by zinc of triphenylphosphine sulfide,which was prepared directly from benzene by reacting it with sulfur and phosphorus trichloride with high yield,pure product and moderate conditions.

Triphenylphosphine was synthesized by the reduction of triphenylphosphine sulfide by iron filings.

Through Friedel-Crafts reaction, We have prepared highly purified triphenylphosphine sulfide by using benzene, phosphorus trichloride, sulfur, and aluminum trichloride, which is desulfurized with metal powder to produce triphenylphosphine.
