Research speed reading in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 7170-01-6
Synthesis of 1-fluoro-2-methoxy-4-nitrobenzene (1023) To a stirred solution of 1-fluoro-2-methoxy-4-nitrobenzene (2.5 g, 14.60 mmol) in DMF (25 mL) under an argon atmosphere were added potassium carbonate (4 g, 29.20 mmol) and 3-methyl-1H-1,2,4-triazole (1.2 g, 14.60 mmol) at room temperature. The reaction mixture was stirred at 85 C. for 16 h in a sealed tube. After consumption of the starting material (monitored by TLC), the reaction mixture was diluted with water (100 mL) and extracted with EtOAc (2×50 mL). The combined organic extracts were dried over sodium sulfate, filtered and concentrated in vacuo. The crude material was purified by column chromatography using 15-25% EtOAc:hexane to afford 1-fluoro-2-methoxy-4-nitrobenzene (1.2 g, 35%) as an off-white solid. 1H-NMR (CDCl3, 400 MHz): delta 8.87 (s, 1H), 8.10 (d, 1H), 8.00-7.97 (m, 2H), 4.10 (s, 3H), 2.50 (s, 3H); LCMS: 234.9 (M+1); (column; Ascentis Express C-18 (50×3.0 mm, 2.7 mum); RT 2.02 min. 0.025% Aq TFA+5% ACN: ACN+5% 0.025% Aq TFA; 1.2 mL/min); TLC: 30% EtOAc:hexane (Rf: 0.2).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 7170-01-6, and we look forward to future research findings.
