Related Products of 1533519-84-4, New Advances in Chemical Research in 2021.Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, 1533519-84-4, name is 4-(4-Cyclopropylnaphthalen-1-yl)-1H-1,2,4-triazole-5(4H)-thione, molecular formula is C15H13N3S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
To a 250 mL reaction flask was added 4-(4-cyclopropylnaphthalen-1-yl)-4Eta-1,2,4-triazole-3-thiol (Compound A, 58, 0.01811101), potassium carbonate (3.748, 0.02711101, 1.569), 01 ^ (5011 ^). Ethyl bromoacetate was added dropwise with stirring (3.3 g, 0.022 mol 1,1.2 eq). After completion of the reaction, the reaction was stirred at room temperature for 1.5 h. Sampling After testing the raw material, the reaction is complete, Should be added to the liquid ice water 1OOmL, a white solid precipitation. Stir for 30min, suction filter, washed. After the cake was dried, the residue was washed with ethyl acetate Recrystallization gave
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-(4-Cyclopropylnaphthalen-1-yl)-1H-1,2,4-triazole-5(4H)-thione is helpful to your research.
