Anwendungen

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.

Bemerkungen

Stable under recommended storage conditions. Incompatible with oxidizing agents.

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.
