New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 7411-23-6
a 3,5-Dibromo-1-(4-methoxyphenylmethyl)-1H-1,2,4-triazole 4-Methoxyphenylmethyl chloride (4.47 ml) was added to a stirred solution of 3,5-dibromo-1,2,4-triazole (7.125 g) and triethylamine (4.81 ml) in anhydrous dichloromethane (70 ml) at room temperature. After 4 days, the mixture was evaporated under reduced pressure and the residue purified by column chromatography over silica, eluding with ethyl acetate/isohexane (1:4) to give the sub-title compound (7.34 g) as a solid. MS (+ve APCI) 346/348/350 ((M+H)+).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3,5-Dibromo-1H-1,2,4-triazole help many people in the next few years.
