Benzoyl Peroxide → HCID 4534807, compound

Participants

Reaction Steps

A mixture of 5-ethylidene-5H-dibenzo[a,d]cycloheptene (10.9 g., 0.05 mole), N-bromosuccinimide (8.9 g., 0.05 mole), benzoyl peroxide (15 mg.) and 150 ml. of carbon tetrachloride is stirred and heated to refluxing on the steam-bath for 4 hours. After cooling, the succinimide is separated by filtration and washed with carbon tetrachloride. The combined filtrate and washings are evaporated to dryness under reduced pressure. Crystallization of the residual solid from petroleum ether gave 5-(2-bromoethylidene)-5H-dibenzo[a,d]cycloheptene in a yield of 10.65 g. (72%), m.p. 87.5°-89.5°C. An analytical sample, after recrystallization from petroleum ether, melted at 89°-90°C.
