Abstract: Seven 2,3-epoxy-1-phenyl-3-aryl-1-propanones were synthesized via epoxidation of the corresponding 1-phenyl-3-aryl-2-propen-1-ones with 30% aqueous hydrogen peroxide in 74-99% yields using benzyldimethyltetradecylammonium chloride as phase transfer catalyst under ultrasound irradiation.

Keywords: Epoxidation; 2,3-epoxy-1-phenyl-3-aryl-1-propanone; phase-transfer catalysis; ultrasonic irradiation.
