Solvent-free synthesis of chalcones and n-phenyl-2-pyrazolines under microwave irradiation

الملخص EN

An environment and economic synthesis of Chalcones 3 under microwave (MW) irradiation has been adopted.

Reaction of compound 3 with phenyl hydrazine under MW irradiation afforded N-phenylpyrazole derivatives 5.

The reaction time has been brought down from hours to seconds with improved yield as compared to conventional heating.
