Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C3H5N3

General procedure: TBHP (3 eq.) was added to a solution of 3-phenyl-1,2,4-triazole (0.4 mmol) 1a, benzaldehyde 2a (0.6 mmol), followed by TBAI (20 mol%) in DCE(4 mL). The reaction mixture was stirred at 120 oC under nitrogen atmosphere for 5 h. After completion of the reaction confirmed by TLC, the reaction mixture was cooled to room temperature and partitioned between water and ethyl acetate. The organic and aqueous layers were then separated and aqueous layer was extracted with ethyl acetate twice. The combined organic extracts were dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the crude. The crude was further purified by silica gel chromatography using EtOAc/hexane as eluents to furnish the desired product 3 or 5.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 7170-01-6, and we look forward to future research findings.
