Reference of 3641-13-2, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 3641-13-2, name is 5-Amino-4H-1,2,4-triazole-3-carboxylic acid, molecular formula is C3H4N4O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
The organometallic complex [Mo(CO)3Br2(NCMe)2] was preparedaccording to literature methods [1,4,5]. A solution of Mo-II(2.3 g, 5.45 mmol) in ethanol (60 mL) was treated with 3-amino-1,2,4-triazole-5-carboxylic acid (ATZAc) (0.70 g, 5.45 mmol). Theresulting solutionwas stirred for 8 h under reflux and evaporated todryness. The solid obtained was washed with hexane and dried under vacuum (2.22 g of yield) [6]. Elemental Analysis forMoC7O3Br2N2H6 (421.94 g/mol): calculated C 19.90%, N 6.63%, H1.42%, Mo 22.73%; found C 19.76%, N 6.59%, H 1.31%, Mo 22.65%. IR(KBr pellet, cm-1): nu (?CO) =1879, 1974, 204, nu (C?O) =1679. EDS(Full scale 37854 ct cursor: -0.348 (octs), keV): C, N, O, Br, Mo.
