m-Chloroperbenzoic acid → HCID 13187947, compound

Participants

Reaction Steps

21 g (0.1 mol) of the (IV) prepared in Example 1 are dissolved in 100 ml of chlorobenzene, and 20 g (0.12 mol) of m-chloroperbenzoic acid in 200 ml of chlorobenzene are added dropwise. The mixture is heated under reflux for 4 hours, and is worked up in the customary manner with sodium bisulphite solution to destroy the excess of per-acid, and sodium bicarbonate solution to separate off the m-chlorobenzoic acid. From the organic phase, 17 g (75%) of 3,3-dichloro-5,6-epoxybicyclo[2,2,1]heptane-2,2-dicarbonitrile were isolated, m.p. 229° C.
