Benzoic Acid → Benzyl dithiobenzoate

Participants

Reaction Steps

A mixture of benzoic acid (1.22 g), benzyl mercaptan (1.24 g) and phosphorus pentasulfide (4.44 g) in toluene (40 ml) was refluxed for 10 h. A dark red color was developed immediately after heating. After the reaction was complete (as monitored by GC-MS), it was cooled to room temperature and purified by column chromatography packed with.neutral alumina, eluting with benzene. Removal of the solvent by distillation gave the single compound, benzyl dithiobenzoate (2.22 g, 91%). It was further characterized by 1H and 13C-NMR.
