Application of 3179-31-5, 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. 3179-31-5, name is 1H-1,2,4-Triazole-3-thiol, molecular formula is C2H3N3S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Step B–Cyclobutylmethyl 1,2,4-Triazol-3-yl Sulfide To a solution of 1,2,4-triazole-3-thiol (20.2 g; 0.20 mol) and sodium methoxide (11.8 g; 0.22 mol) in methanol (250 ml) is added cyclobutylmethyl methanesulfonate (36.4 g; 0.22 mol). The mixture was refluxed for 27 h under dry nitrogen, allowed to cool to 25 C. and filtered. The solid was washed with ethyl acetate and the organic solutions combined and evaporated. The residue was dissolved in water (250 ml) and extracted into ethyl acetate (250 ml) and dichloromethane (100 ml). The extracts were combined, dried (Na2 SO4), filtered and evaporated to afford crude cyclobutylmethyl 1,2,4-triazol-3-yl sulfide (21.8 g; 65%) as a white, sticky solid. NMR -d(CDCl3; 60 MHz) 1.5-2.8 (m), 3.2 (2H, d, J=7 Hz), 8.0 (1H, s) and 12.4 (1H, br s).
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 1H-1,2,4-Triazole-3-thiol.
