What is the synthesis method of dimethyl 2,3,5,6-tetrachlorobenzene-1,4-dicarboxylate?
To prepare dibenzyl\ (2,3,5,6 -\) tetrafluoroaniline\ (-1,4 -\) dicarboxylic anhydride, you can follow the following method:
First take an appropriate reaction vessel, wash and dry it. Add an appropriate amount of a compound containing\ (2,3,5,6 -\) tetrafluoroaniline structure to it, and then add a reagent that can introduce dibenzyl, such as benzyl halide and the like, and then add a suitable base, such as potassium carbonate, etc. At a certain temperature, such as under moderate heating and stirring conditions, so that it fully reacts. This step is to smoothly replace the benzyl group in the corresponding position to generate the\ (2,3,5,6 -\) tetrafluoroaniline derivative containing dibenzyl.
Then, the resulting product is properly processed, separated and purified. Pure dibenzyl-containing\ (2,3,5,6 -\) tetrafluoroaniline can be obtained by means such as column chromatography and recrystallization.
Next, take this pure product and place it in another reaction system, add a reagent that can promote its oxidation and carboxylation reaction, for example, in the presence of a suitable catalyst, introduce carbon dioxide gas, and control the appropriate reaction temperature and pressure. After this step of reaction, it is introduced into the carboxyl group at the\ (1,4 -\) position to generate dibenzyl\ (2,3,5,6 -\) tetrafluoroaniline\ (-1,4 -\) dicarboxylic acid.
Finally, the dicarboxylic acid product is mixed with an appropriate amount of dehydrating agent, such as acetic anhydride, etc., heated and refluxed to promote its dehydration reaction, and then closed the loop to form dibenzyl\ (2,3,5,6 -\) tetrafluoroaniline\ (-1,4 -\) dicarboxylic anhydride. After the reaction is completed, the target product can be obtained after a series of operations such as cooling, separation and purification. The whole process needs to pay attention to the precise control of the reaction conditions, and the separation and purification after each step of the reaction must be fine to ensure the purity and yield of the final product.
