Application of 27996-86-7, 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, 27996-86-7, name is 4-[1,2,4]Triazol-1-yl-benzaldehyde, molecular formula is C9H7N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
The intermediate products, 4-(1H-1,2,4-triazol-1-yl)benzaldehyde (TABA), were prepared from 1,2,4-triazole and 4-fluorobenzaldehyde as literature reported. The mixture of TABA (2.424 g, 14 mmol) and 3,4-diaminobenzoic acid (2.890 g, 19 mmol) in 25 mL toluene was refluxed for 4 h at 110 C, then cooled to 5 C and kept on stirring for 15 min, dark yellow precipitate was collected and washed with ice-cold toluene and diethyl ether. The golden yellow microcrystal L1 ligand can be obtained by refluxing the previous precipitate in 70 mL MeOH at 50 C for 10 min (yield: 2.014 g, 46.8%). Elemental analysis: Calc. for C16H13N5O2: C, 62.53; H, 4.26; N, 22.79. Found: C, 62.59; H, 4.30; N, 22.71%. IR (KBr) numax = 3456, 3338, 3152, 2926, 2900, 2800, 2625, 2586, 2555, 2517, 2025, 1680, 1605, 1524, 1410, 1296, 1267, 1210, 1148, 968, 872, 829, 768, 669, 522, 420 cm-1.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 27996-86-7.
