dibenzoyl disulphide Chemical Properties,Uses,Production

Uses

Benzoyl Disulfide (cas# 644-32-6) is a useful reactant for the green preparation of amides and amines.

Purification Methods

About 300mL of solvent is blown off from a filtered solution of dibenzoyl disulfide (25g) in acetone (350mL). The remaining acetone is decanted from the solid which is recrystallised first from 300mL of 1:1 (v/v) EtOH/ethyl acetate, then from 300mL of EtOH, and finally from 240mL of 1:1 (v/v) EtOH/ethyl acetate. The yield is about 40% [Pryor & Pickering J Am Chem Soc 84 2705 1962]. [Beilstein 9 H 424, 9 II 289, 9 III 1977.] Handle in a fume cupboard because of TOXICITY and obnoxious odour.
