Category: Triazoles

Research speed reading in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 162848-16-0, name is 4-[1,2,4]Triazol-1-yl-benzoic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 4-[1,2,4]Triazol-1-yl-benzoic acid

General procedure: To a solution of benzoic acid derivative (0.50 mmol, 1 equiv.) in CH2Cl2 (7.5 mL) cooled in an ice-bath, Et3N (1.50 mmol, 3 equiv.) and TBTU (0.65 mmol, 1.3 equiv.) were added. After 10 min, the corresponding amine (0.50 mmol, 1 equiv.) was added, and the reaction mixture was left to react for 1 h at room temperature. The reaction mixture was diluted with CH2Cl2 (30 mL) and the organic phase was washed with 1 M aqueous HCl (3 15 mL), saturated aqueous solution of NaHCO3 (3 15 mL), and brine (30 mL), and dried over Na2SO4. The solvent was evaporated under reduced pressure.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 162848-16-0

Synthetic Route of 10570-40-8, New Advances in Chemical Research in 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 10570-40-8, name is 4-Methyl-4H-1,2,4-triazole, molecular formula is C3H5N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.

A solution of 4-methyl-1,2,4-triazole (0.55 g, 6.6 mmol) and CH3I (2.1 g, 15 mmol) in MeOH (1.5 mL) was heated in a pressure vessel (bath temperature 100 C) for 1 h. After cooling the solvent was evaporated. The residue was suspended in Et2O, filtered and dried to yield a gray powder (1:27 g, 85%). The spectroscopic data were as previously reported [49].

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 4-Methyl-4H-1,2,4-triazole is helpful to your research.
