Abstract
A rapid, efficient, clean and environmentally
benign exclusive synthesis of a series of
4-substituted-3-Phenylsydnones has been developed using
Friedel-Craft reaction with an excellent yields under microwaves
irradiation. The results are compared with conventional heating.
Structural assignments are based on physical, analytical and
spectroscopic data (IR, 1H-NMR &13C-NMR).
Keywords: Green chemistry, Microwave irradiation, Sydnones,
Friedel-Craft reaction.
