Research speed reading in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 288-36-8, name is 1H-1,2,3-Triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Safety of 1H-1,2,3-Triazole
In a round-bottomed flask equipped with an overhead magnetic stirrer, reflux condenser, and nitrogen inlet were added 5-chloro-2-iodobenzoic acid (1 .15 g, 4.07 mmol), copper iodide (0.04 g, 0.2 mmol), and CS2CO3 (2.65 g, 8.14 mmol). To these solids were added dioxane (6 mL), water (0.05 mL), then 1 H-1 ,2,3-triazole (0.47 mL, 8.14 mmol), and finally trans-1 ,2-dimethylcyclohexane-1 ,2-diamine (0.3 mL, 0.81 mmol). The mixture was then warmed to 100 C for 4 hrs. Then the mixture was cooled and then MTBE and of water were added. After vigorous mixing, the layers were separated and the bottom aqueous layer was acidified to pH 2 with 6N HCI. The aqueous was then extracted twice with EtOAc. The combined organic layers were dried, filtered, and concentrated. The oil was stirred overnight in EtOAc (8 mL) and the resulting precipitate was removed by filtration affording a first crop of wanted product(100 mg). The mother-liquors were concentrated and purified by FC on S1O2 column (eluting from DCM to DCM : MeOH: 90: 10) to afford a second batch of the desired product that was mixed with the former to afford 5-chloro-2-(2H-1 ,2,3-triazol-2- yl)benzoic acid (p120, 620 mg, y=68%). MS (mlz): 223.9 [MH]+
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1H-1,2,3-Triazole, in my other articles.
