Versuchsvorschrift

1.040 g (5 mmol) of chalcone was dissolved in 15 ml of ethanol and to the solution was added 2 ml of 25% hydrogen peroxide and 2 ml of an aqueous solution of 1 M sodium carbonate. The precipitate which was formed after stirring for 3 h was isolated and recrystallized from DMSO-water to give 250 mg (22%) of chalcone epoxide.
