1,3-Dipolar Cycloaddition of Nitriles under Microwave Irradiation in Solvent-Free Conditions
摘要:
Several nitriles were allowed to react with nitrones or nitrile oxides in the absence of solvent under microwave irradiation within 2-10 min to give 2,3-dihydro-1,2,4-oxadiazoles or 1,2,4-oxadiazoles, respectively.
