Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 122-05-4, name is Pyrazine-2,5-dicarboxylic acid, A new synthetic method of this compound is introduced below., name: Pyrazine-2,5-dicarboxylic acid
5 mmol of (DMFQ)2Ir(Cl)2Ir(DMFQ)2, 25 mmol of pyrazine-2,5-dicarboxylic acid (Py2CA), and 50 mmol of potassium carbonate were mixed in 100 mL of 1,2-dichloroethane, and refluxed for 24 hours under a nitrogen atmosphere. After the reaction was complete, the solution was cooled down to about 50 C., and filtrated. The filtrated solution was purified by using column chromatography to thereby produce (DMFQ)2Ir(Py2CA)Ir(DMFQ)2 at a yield of 82%.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
