ABSTRACT


TThis paper describes novel agro-waste derived Water Extract of Orange Fruit Shell Ash (WEOFSA) catalyzed synthesis of 5-aryl-1,2,4-triazolidine-3-thiones and 1,2,4-triazospiro-3-thiones under microwave irradiation. Herein, we have developed inexpensive, facile and green method synthesis of cyclic thiones by the reaction of aromatic aldehyde and cyclic ketone, with thiosemicarbazide in presence of agro-waste derived catalyst. The obtained product is chromatographically pure after recrystallization from ethanol, and final product is characterized by various spectroscopic techniques FT-IR, 1H-, 13C-NMR and HR-MS.
