-
Paragraph 0037-0039, (2021/08/11)
The invention provides a preparation method of a diaryl-substituted chlorotriazine OLED intermediate, and the method comprises the following steps: S1, carrying out heating reaction on an aryl nitrile compound and urea in an organic solvent under the action of strong alkali, and carrying out intermolecular ring closing to form a diaryl hydroxyl triazine compound; S2, enabling the diaryl hydroxyl triazine compound obtained in the step S1 to be subjected to a reaction under the action of phosphorus oxychloride, and obtaining the diaryl chlorinated triazine compound. According to the method, the final product can be obtained only through two-step reaction, raw materials are cheap, and expensive catalysts are not needed. The method has the characteristics of low cost, few steps, high yield, few three wastes, easiness in operation, environment friendliness, suitability for industrialization and the like.
Method for synthesizing 1, 3, 5-triazine derivative
-
Paragraph 0109-0112, (2021/07/28)
The invention relates to a method for synthesizing a 1, 3, 5-triazine derivative, which is used for synthesizing a 1, 3, 5-triazinone compound and a 2, 4, 6-trisubstituted-1, 3, 5-triazine compound containing three different substituent groups. Synthesis of the 1, 3, 5-triazinone compound comprises the following steps: taking amide, oxalyl chloride and amidine as reaction substrates, and heating for reaction; the synthesis method of the 2, 4, 6-trisubstituted-1, 3, 5-triazine compound containing three different substituent groups comprises the following synthesis steps: by taking amide, oxalyl chloride and amidine as reaction substrates, heating and reacting to obtain a 1, 3, 5-triazinone compound; reacting the 1, 3, 5-triazinone compound, phosphorus oxychloride and triethylamine in acetonitrile to generate a 2-chloro-4, 6-disubstituted 1, 3, 5-triazine compound; and coupling the 2-chloro-4, 6-disubstituted 1, 3, 5-triazine compound with various nucleophilic reagents, so that the 2, 4, 6-trisubstituted-1, 3, 5-triazine compound containing three different substituent groups is prepared. The method is wide in application range and relatively high in reaction yield, provides a new way for synthesis of the 1, 3, 5-triazine derivative, and has a relatively strong industrial application prospect.
