3-(7-oxooxepan-2-yl)propanenitrile

反应条件: temp:55.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A reactor is loaded with 151 g of 3-(2-cyclohexanonyl)propionitrile in 500 ml of n-hexane and 260 g of m-chloroperbenzoic acid (70% titer) dissolved at 50° C. in 2000 ml of n-hexane in 30 minutes. The solution is heated to 55° C. for 15 hours. Cooling of the solution separates, in crystalline form, part of the m-chlorobenzoic acid which is scarcely soluble in the system, together with a heavy liquid phase which is formed by 7-cyanoethyl-2-oxepanone and by m-chlorobenzoic acid. 71.5 g of 7-cyanoethyl-2-oxepanone, impure with m-chlorobenzoic acid, are recovered from the lower phase. 24 g of 7-cyanoethyl-2-oxepanone are recovered from the upper phase by concentration and several crystallizations. Conversion over the initial ketone is 85%. Yield on the converted amount is 57%.
