The reaction of aromatic thiols with sulfur dichloride and sulfur monochloride to form the corresponding aromatic trisulfides, 2a-d, and tetrasulfides, 3a-d, has been optimized with respect to yield and purity. The use of pyridine as an amine base and the
Desulfurization of Organic Trisulfides by Tris(dialkylamino)phosphines. Mechanistic Aspects

Tris(dialkylamino)phosphines effect a rapid desulfurization of trisulfides to disulfides under mild conditions.The reaction mechanism involves a bimolecular process, proceeding by the rate-determining formation of a phosphonium salt intermediate.The central sulfur atom of a diaryl trisulfide is removed in the process, while a dialkyl trisulfide loses a terminal sulfur atom to the aminophosphine.
