FormLiquid
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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
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.
Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
