Diphenyl disulfide is one of the most popular organic disulfides used in organic synthesis. It is used as a reagent for the α-phenylsulfenylation of carbonyl compounds. It participates in hydrothiolation of alkynes via amine-mediated single electron transfer mechanism. It is the hydrolysis product of dyfonate.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Sulfenylation agent for enolates of ketones, esters or carboxylic acid dianions: J. Am. Chem. Soc., 95, 6840 (1973); 98, 4887 (1976); Chem. Rev., 78, 363 (1978). Oxidation to the sulfoxide and thermal elimination can be used for the conversion of ketones to enones via thermal sulfoxide elimination, less frequently used than the selenoxide route (cf preceding entry), due to the higher temperatures required.
