Application of 288-36-8, New Advances in Chemical Research in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 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.
A solution of 2-iodobenzoic acid (3.0 g, 12.09 mmol) in DMF (1.0 mL) was treated with 1,2,3-triazole (1.5 g, 21.7 mmol), copper(I) iodide (0.25 g, 1.2 mmol), Cs2CO3 (7.08 g, 21.7 mmol), and trans-N,N?-dimethylcyclohexane-l ,2-diamine (0.31 g, 2.17 mmol). The mixture was heated at 120 CC for 12h. The reaction was cooled to ii, diluted with EtOAc, and filtered through Celite. The residue was purified by gradient elution on Si02 (0 to 10% MeOH in DCM with 0.1% AcOH) to give the title compound.?HNMR (500 MHz, DMSO-d6) 3 13.05 (br s, 1H), 8.12 (s, 2H), 7.81-7.52 (m, 4H) ppm. LRMS m/z (M+H) 190.2 found, 190.2.
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.
