Synthetic Route of 74205-82-6, 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. 74205-82-6, name is (1H-1,2,4-Triazol-1-yl)methanol, molecular formula is C3H5N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
The indoline (1) (10.0 (^, 0.08311101) was added to a 11 round bottom flask, Glacial acetic acid 1001111, stirring at room temperature 0.5h, adding triazole methyl alcohol (16.61 g, 0.167 mol), and the reaction was stirred at 80 C for 3 h. TLC indicated that the reaction was complete and stopped The reaction was cooled to room temperature, 40% aqueous sodium hydroxide (100 ml) and 100 ml of methanol were added under ice-cooling, refluxed for 0.5 h at 70 C, Dichloromethane (75 mL x 3), saturated brine (150 ml x 2), dried over anhydrous sodium sulfate and concentrated to give Yellow oil 7.74 g (2), yield 46.6%
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 74205-82-6.
