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. 288-88-0, name is 1H-1,2,4-Triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 288-88-0
EXAMPLE 108 1-phenyltriazole 1 g (0.0145 mol) triazole 2, 0.21 g (0.00145 mol) copper(I)oxide, 0.29 g (0.00145 mol) phenantroline monohydrate and 6.01 g (0.044 mol) potassium carbonate are weighed into a Schlenk flask. After repeated evacuating and flushing with argon, 10 ml dry DMF is added. Evacuating and flushing with argon are repeated several times. Subsequently, 2.42 ml (4.43 g, 0.022 mol) of iodobenzene is added. The reaction mixture is stirred for 48 h at 100 C. under argon. After cooling 20 ml DCM is added and filtered. The solvent is removed in vacuum and the product is obtained after purification by column chromatography (KG 60, gradient petroleum ether/EtOAc 8:2 to EtOAc) as a yellowish-white solid.M 145.17 C8H7N3 Yield: 1.362 g (65%)1H-NMR DM-94 (300 MHz/DMSO): (ppm)=7.41 (t, 1H, 6-H); 7.58 (t, 2H, 5/5′-H); 7.87 (d, 2H, 4-H); 8.25 (s, 1H, 1-H); 9.31 (s, 1H, 2-H)13C-NMR DM-94 (75.475 MHz/DMSO): (ppm)=119.37 (5/5′-C); 127.78 (6-C); 129.77 (4/4′-C); 136.74 (3-C); 142.27 (2-C); 152.39 (1-C)
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-1,2,4-Triazole, in my other articles.
