Reference of 7170-01-6, New Advances in Chemical Research in 2021. 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, 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.
Example 48 b. 3-methyl-l-(4-nitrophenyl)-lH-l,2,4-triazole3-methyl-lH-l,2,4-triazole (648 mg, 7.8 mmol) and potassium carbonate (2.0 g, 14.2 mmol) were added to a solution of l-fluoro-4-nitro-benzene (1.0 g, 7.1 mmol) in DMF (10 mL). The reaction mixture was heated in a sealed tube at 800C overnight, cooled to room temperature and filtered through a pad of Celite. The solids were washed with dichloromethane and the filtrate was concentrated under reduced pressure. The residue was taken in water and the resultant precipitate was collected by filtration, washed with water and dried under high vacuum to afford 950 mg of the title compound (67 % Yield). 1H NMR (400 MHz, CHLOROFORM-d) delta ppm 2.51 (s, 3 H) 7.83 -7.89 (m, 2 H) 8.36 – 8.41 (m, 2 H) 8.58 (s, 1 H). MS m/z: 205 [M+l]+ .
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 3-Methyl-1H-1,2,4-triazole is helpful to your research.
