General procedure: Dimedone (0.14 g, 1 mmol), benzaldehyde (0.1 g, 1 mmol), and 4-phenylurazole (0.177 g, 1 mmol) were mixed with PEG-SO3H (0.6 g, 0.1 mmol) and the obtained mixture was stirred magnetically at 80 C for 40 min. After the completion of the reaction warm water (20 mL) was added and the mixture stirred for about 5 min. The insoluble crude product was filtered and recrystallized from EtOH/H2O 4:1 and the pure product was obtained (0.352 g, 91%). In order to recover the catalyst, the filtrate was dried under reduced pressure and recovered catalyst was washed with diethyl ether and reused after drying under reduced pressure. The equivalent procedure was used for the synthesis of triazolo[1,2-a]indazole-tetraones.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4-Phenyl-1,2,4-triazolidine-3,5-dione, in my other articles.
