Electric Literature of 15988-11-1, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 15988-11-1, name is 4-Phenyl-1,2,4-triazolidine-3,5-dione, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A mixture of dimedone (1 mmol), aldehyde or isatin (1 mmol) and 4-phenylurazole (1 mmol), and catalyst (0.01 g, 5 mol%) in water (5 mL) was refluxed. After completion of the reaction that was monitored by TLC (EtOAc:n-hexane, 1:3), the reaction mixture was cooled to room temperature. Then, the precipitated product was filtered and washed with water and cooled with ethanol to afford the pure product.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 4-Phenyl-1,2,4-triazolidine-3,5-dione.
