Reaction Steps

19.90 g (0.11 mol) of 5-(2-propenyl)-1,3-benzodioxole were initially introduced into a double-walled flask having a stirrer and reflux condenser and are warmed to 40° C. 43.58 g (0.10 mol) of a 20.58% strength solution of perpropionic acid in benzene were added dropwise, whilst stirring, and stirring was continued at this temperature for a further 5 hours. Titrimetric analysis then showed a peracid conversion of 98%. Analysis of gas chromatography gave a selectivity for the 5-(oxiranylmethyl)-1,3-benzodioxole formed of 61%.
