Water → 2-Phenylsulphenyl-4-trifluoromethylbenzonitrile

Participants

Reaction Steps

A mixture of 2-nitro-4-trifluoromethylbenzonitrile (8.64 g), thiophenol (4.4 g) and potassium carbonate (6.9 g) in acetonitrile was heated at reflux for 4 hours. After cooling, the mixture was poured into water and extracted with dichloromethane. The organic extract was dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure. The residue was triturated with hexane to give 2-phenylsulphenyl-4-trifluoromethylbenzonitrile as a white solid (9.5 g), m.p. 51° C.
