Electric Literature of 288-88-0, 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. 288-88-0, name is 1H-1,2,4-Triazole belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 1,2,4-triazole (4.06 g, 58.7 mmol), potassium carbonate (9.05 g, 65.5 mmol), 4-fluorobenzaldehyde (6.3 ml, 58.7 mmol), and copper(I) oxide (0.26 g, 1.82 mmol) in pyridine (30 ml) is heated under nitrogen atmosphere at reflux overnight. After pyridine is distilled, the residue is diluted with chloroform, filtered, and washed with chloroform. The combined filtrate is washed with water, dried over magnesium sulfate, and concentrated in vacuo. The crude material is purified by column chromatography on silica with hexane/ethyl acetate (1:2) to give 4-(1,2,4-triazol-1-yl)-benzaldehyde and with ethyl acetate/methanol (19:1) to give 4-(1,3,4-triazol-1-yl)-benzaldehyde.
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, 1H-1,2,4-Triazole, other downstream synthetic routes, hurry up and to see.
