Application of 27996-86-7, 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. 27996-86-7, name is 4-[1,2,4]Triazol-1-yl-benzaldehyde, molecular formula is C9H7N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.

General procedure: To a glass vessel suitable for sealing with Teflon cap (for microwave vials) were added 1-(chloromethyl)-4,5-dimethoxy-2-nitrobenzene (1 equiv.) [34] and benzaldehyde derivative (3 equiv.) The vessel was capped and then evacuated and backfilled with N2 (thrice-repeated process). Anhydrous DMF (3.5mL/mmol) was introduced and the solution was vigorously stirred for 20minat-20C. TDAE (1.06 equiv.) was added slowly and the mixture was stirred for one hour. Then, the reaction was stirred at room temperature overnight. After LC-MS analysis clearly showed that the chloride had been totally consumed, the reaction was hydrolyzed with water. The mixture was then extracted with ethyl acetate. The combined organic layers were washed with water and brine, dried over Na2SO4, filtered off, and concentrated under reduced pressure to afford the corresponding crude product.

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-benzaldehyde is helpful to your research.
