SYNTHESIS OF 1H-INDAZOLES USING LEMON PEEL POWDER AS A NATURAL, GREEN AND EFFICIENT CATALYST UNDER ULTRASOUND IRRADIATION
Bioactive 1H-indazoles were synthesized from 2-substituted aromatic aldehydes and hydrazine hydrate using DMSO and lemon peel
powder as a green and efficient natural catalyst. In comparison to other reported conventional methods, this method affords good yield
under ultrasonic irradiation.
