Related Products of 15988-11-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 15988-11-1, name is 4-Phenyl-1,2,4-triazolidine-3,5-dione belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below.
General procedure: General procedure: A mixture of 4-phenylurazole (1, 1 mmol), aryl aldehyde (2, 1.1 mmol) or ketone (5, 1.1 mmol), 1,3-diketone (3, 1 mmol) and FeCl3 (16.2 mg, 10 mol%) in acetonitrile (2.5 mL) was stirred in preheated oil bath at reflux for a specified time as required to complete the reaction (see Table 2 and 3). After complete conversion, as indicated by TLC, the solvent was removed in vacuo and the residue was diluted with water and extracted with ethyl acetate (2¡Á10 mL). The combined organic layers were dried over anhydrous Na2SO4, concentrated in vacuo and purified by column chromatography on silica gel (Merck, 60-120 mesh, ethyl acetate:hexane, 4:6) to afford the pure triazolo[1,2-a]indazoletrione or spirotriazolo[1,2-a]indazoletetraonederivative.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Phenyl-1,2,4-triazolidine-3,5-dione, other downstream synthetic routes, hurry up and to see.
