Reference of 288-88-0, New Advances in Chemical Research 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, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Example 91: Preparation of 4-(lH-l,2,4-triazol-l-yl)benzaldehyde (DI5) To a stirring solution of 4-fluorobenzaldehyde (10.0 g, 80.6 mmol) in DMF (150 mL) were added K2CO3 (13.3 g, 96.7 mmol) and 1,2,4- triazole (6.67 g, 96.7 mmol) and the resultant reaction mixture was stirred at 120 C for 6 h. After completion of reaction (by TLC), the reaction mixture was diluted with H20 and extracted with EtOAc (3 xlOO mL). The combined EtOAc layer was washed with H20 and brine, dried over Na2S04, and concentrated under reduced pressure to afford the title compound as a solid (9.0 g, 65%): mp 145-149 C: ]H NMR (400 MHz, CDC13) delta 10.08 (s, IH), 8.70 (s, IH), 8.16 (s, IH), 8.06 (d, J = 8.0 Hz, 2H), 7.92 (d, J = 8.0 Hz, 2H); ESIMS m/z 173.9 ([M+H]+).
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 1H-1,2,4-Triazole, hurry up and to see.
