EFFECT OF SOLVENT POLARITY ON THE RATES AND PRODUCT RATIOS OF MICROWAVE INDUCED DIELS-ALDERREACTION

Department of Chemistry Yunnan University Kunming 650091

Received Date: 17 October 1994

The rates and yields of two Diels-Alder reactions, employing a series of different solvents as the energy-transfer medium under microwave irradiation (frequency, 2450 MHZ) and conventional refluxing at ambient pressure, have been compared The more polar the solvent used, the more increasing in yield was got by microwave irradiation.
