-
Paragraph 0059-0066, (2021/06/26)
The invention provides a preparation method of a s-triazine derivative, which is characterized in that an aryl nitrile compound is used as a substrate, lithium bis (trifluoromethanesulfonimide) is used as a catalyst, and the s-triazine derivative is obtained through a cyclopolymerization reaction. Compared with the prior art, the method has the advantages that a catalytic system is simple and easy to obtain, too high or too low rigorous reaction temperature is not needed, the reaction condition is mild, the reaction time is short, the post-treatment is simple, and the obtained s-triazine derivative has very high yield and is suitable for large-scale production.
