설명
Lactonization of olefins with monomethyl ester of malonic acid and ceric ammonium nitrate was carried out in acetic acid and in acetonitrile under simple mechanical stirring or ultrasound irradiation. Lactonization of olefins with CAN and monomethyl ester of malonic acid under ultrasound irradiation shows an acceleration with respect to the analogous mechanically stirred reaction.
