Azobisisobutyronitrile → HCID 19001555, compound

Participants

Reaction Steps

38.1 g (0.2 mol) of 4-methylbenzenesulphonyl chloride are dissolved in 300 ml of carbon tetrachloride and treated with 35.6 g (0.2 mol) of N-bromosuccinimide and, after addition of 0.2 g (1.2 mmol) of azobisisobutyronitrile (ABU), the mixture is heated under reflux for 4 h. After cooling, the solids are filtered off and the filtrate is freed from the solvent. Flash chromatography (petroleum ether/toluene 4:1, 50 μm particle size) and subsequent recrystallisation from 100 ml of cyclohexane gives 24.0 g (45% of theory) of the title compound. Rf =0.75 (toluene)
