One-pot Multicomponent Synthesis Of Triazolo[1,2-a]Indazole-triones Using Nanoperovskite catalyst As An Efficient Catalyst Under microwave Condition

In this work Synthesis of triazolo[1,2-a]indazole-triones derivatives by an one-pot three-component reaction of phenyl urazole , dimedone and aromatic aldehydes under microwave irradiation and solvent- free conditions using La0.5Ca0.5CrO3 Perovskite as catalyst is described. reactions are completed in short time and products are obtained in high yields, and catalyst are separated easily.
