Triphenylphosphine sulfide (IUPAC name: triphenyl-λ 5-phosphanethione) is the organophosphorus compound with the formula (C 6 H 5) 3 PS, usually written Ph 3 PS (where Ph = phenyl). It is a colourless solid, which is soluble in a variety of organic solvents.
Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C 6 H 5) 3 and often abbreviated to P Ph 3 or Ph 3 P. It is versatile compound that is widely used as a reagent in organic synthesis and as a ligand for transition metal complexes, including ones that serve as catalysts in organometallic ...
A phosphine sulfide is an organophosphorus compound with the formula R 3 PS. They are typically colorless, air-stable solids. A common example of a tertiary phosphine sulfide is triphenylphosphine sulfide. Phosphine sulfides are sometimes intermediates in the synthesis of tertiary phosphines. Phosphine sulfides are tetrahedral.

In the laboratory, diphenylphosphine is a common intermediate. It can be deprotonated to give diphenylphosphide derivatives: [2] Ph 2 PH + n BuLi → Ph 2 PLi + n BuH. The preparation of phosphine ligands, Wittig-Horner reagents, and phosphonium salts are commonly accomplished by alkylating diphenylphosphine.
