Synthetic Route of 27996-86-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 27996-86-7, name is 4-[1,2,4]Triazol-1-yl-benzaldehyde, This compound has unique chemical properties. The synthetic route is as follows.
Example 94 Preparation of 1-(4-Vinylphenyl)-1H-1,2,4-triazole (DI59) To a stirred solution of 4-[1,2,4]triazol-1-yl-benzaldehyde (9.0 g, 52 mmol) in 1,4-dioxane (100 mL), were added K2CO3 (10.76 g, 78 mmol) and methyl triphenyl phosphonium bromide (22.2 g, 62.4 mmol) at room temperature. The resultant reaction mixture was heated to 70 C. for 18 h. After completion of the reaction (TLC), the reaction mixture was cooled to room temperature and filtered and the obtained filtrate was concentrated under reduced pressure. Purification by flash chromatography (SiO2, 100-200 mesh; 25-30% EtOAc in petroleum ether) to afforded the title compound as a white solid (5.6 g, 63%): ESIMS m/z 172.09 ([M+H]+).
The chemical industry reduces the impact on the environment during synthesis 4-[1,2,4]Triazol-1-yl-benzaldehyde. I believe this compound will play a more active role in future production and life.
