Storage & Sensitivity
Keep Cold.


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.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
