In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 94-97-3, name is 5-Chloro-1H-benzo[d][1,2,3]triazole belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 5-Chloro-1H-benzo[d][1,2,3]triazole
A solution of 5-chloro-1H-benzotriazole (1.53 g) in THF was added at 0 C. to a mixture of diisopropylic azodicarboxylate (2 mL), triphenyl phosphine (2.9 g) and allyl alcohol (1.4 mL) in THF. After stirring one hour at 0 C., the mixture was concentrated under reduced pressure to give a residue that was purified by chromatography (SiO2, heptane/EA) to afford 2-allyl-5-chloro-2H-benzotriazole (1.02 g, 53%). A mixture of 1-allyl-5-chloro-1H-benzotriazole and 1-allyl-6-chloro-1H-benzotriazole was also recovered (0.9 g, 47%).
The synthetic route of 94-97-3 has been constantly updated, and we look forward to future research findings.
