Azobisisobutyronitrile → 1(3H)-Isobenzofuranone, 3-bromo-

Participants

Reaction Steps

1H-Isobenzofuran-3-one (40.2 g, 0.3 moles), N-bromosuccinimide (53.4 g., 0.03 moles) and azo-bisisobutyronitrile (1g) were combined in 500 mL of CCl4 and refluxed under nitrogen for 2 hours. The reaction mixture was cooled to room temperature, filtered and the filtrate concentrated in vacuo to a solid residue. The latter was crystallized from cyclohexane to yield title product, 34.5 g., m.p. 78°-80° C.
