Application of 288-36-8, 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. 288-36-8, name is 1H-1,2,3-Triazole, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
To a solution of 2-iodobenzoic acid (3.0 g, 12.1 mmol) in DMF was added 1,2,3- triazole (1.5 g, 21.7 mmol), Cs2C03(7.1 g, 21.7 mmol), Cul (114 mg, 0.6 mmol), and trans-N,K- dimethylc)rclohexane-l,2-diamine (310 mg, 2.2 mmol). After heating at 120 C for 10 min in a microwave reactor, the mixture was cooled to room temperature, diluted with EtOAc, and filtered through Celite. The filtrate was concentrated in vacuo and the crude residue was purified by silica gel chromatography (MeOH in DCM with 0.1% AcOH) to give Intermediate H as the faster eluting isomer. 1H NMR (DMSO-d6 , 500MHz) delta 13.05 (brs, 1 H), 8.12 (s, 2H), 7.81-7.52 (m, 4H).
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-1,2,3-Triazole.
