Method for continuously synthesizing benzothiadiazole compound
-
Paragraph 0035-0038, (2020/06/02)
The invention discloses a method for continuously synthesizing a benzothiadiazole compound, comprising the following step: by using an o-mercaptoaniline compound, sodium nitrite and water as reactionsubstrates in a continuous flow reactor, a diazotization-coupling reaction is carried out at certain temperature under certain pressure to obtain the benzothiadiazole compound. By adopting the technology, no protonic acid participates, and water is used as a reactant and a solvent, so that the method is green and environment-friendly. The continuous flow reactor is used, online materials are small, the process is intrinsically safe, and the method is suitable for large-scale production.

-
Paragraph 0077-0080, (2017/11/18)
The invention discloses a synthesis method of a 1,2,3-diazosulfide compound. A o-aminothiophenol compound with a structure shown as a formula (I) and tert-butyl nitrite are taken as raw materials, and are subjected to intramolecular diazo-reaction to obtain the 1,2,3-diazosulfide compound with a structure shown as a formula (II); a reaction equation is as follows (shown in the description), wherein R=hydrogen, fluorine, chlorine, ester group, nitro or methyl. The synthesis method has the beneficial effects that (1) the operation is simple and convenient in a preparation process, an obtained product is easy for after-treatment, and large-scale industrialized production is suitable; (2) reaction conditions are mild; (3) the synthesis cost is lowered; (4) a reaction substrate is high in functional group tolerance, is wide in range and easy to prepare; (5) the reaction is efficient, the yield is high, and the reaction efficiency is higher after reaction amplification; (6) environment pollution is avoided, and environment friendliness is achieved.
