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. Application In Synthesis of 1H-1,2,3-Triazole
A solution of 2-iodo-5-methylbenzoic acid (4.0 g, 15.3 mmol) in DMF (10 mL) was treated with 1 ,2,3-triazole (2.1 g, 30.5 mmol), CsCO3 (9.95 g, 30.5 mmol), CuI (0.145 g, 0.76 mmol) and trans-N,N’-dirnethylcyclohexane-l,2-diamine (0.43 g, 3.05 mmol). The mixture was heated at 120 0C for 10 min in a microwave reactor. The reaction was cooled to rt, diluted with water, and washed with EtOAc. The aqueous phase was acidified with IN HCl and extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by gradient elution on SiO2 (0 to 50% EtOAc in water with 0.1% TFA) to give the desired A-3. A portion of this acid (0.1 1 g, 0.53 mmol) was treated with thionyl chloride (0.59 g, 5.3 mmol) in dichloromethane (5.0 mL) at rt. After stirring at RT for 1 h, the mixture was concentrated, azeotroping with benzene to yield acid chloride A-3.
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.
