Reference of 6523-49-5, 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. 6523-49-5, name is 4-(1,2,4-Triazol-1-yl)aniline, molecular formula is C8H8N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Example B3; Preparation of (compound 3); Reaction under Argon flow. Dry DMSO (0.5 ml) was added to a mixture of intermediate 5 (0.000428 mol) and 4-(lH-l,2,4-triazol-l-yl)-benzenamine (0.000642 mol). The reaction mixture was stirred for 6 hours at 100 C on an oil-bath (no result; only starting material). Cs2CO3 (0.227 g, 1.5 equiv) was added and the reaction mixture was stirred for 3 hours at 100 0C. This mixture was extracted with a mixture of EtOAc/NaHCO3/H2O/NaCl. The extract’s solvent was evaporated. The residue (0.172 g) was washed with diethyl ether, a mixture of diethyl ether/DCM, then purified by EPO
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-(1,2,4-Triazol-1-yl)aniline is helpful to your research.
