Irradiation of Tungsten Light: A Useful Energy Source for Synthesis of 4,5-Dihydro-pyrazole-1-carbaldehyde Derivatives

Abstract

In the present communication, reported the easy, convenient route for the synthesis of N-formyl pyrazolines from α, β-unsaturated ketone. The aqueous 2-methoxyethanol was used as reaction media for the synthesis of titled compounds. All synthesized compounds were confirmed on the basis of IR, 1H NMR, 13C NMR and CHN analysis.
