[0024] Synthetic preparation method of triarylamine double maleimide containing diamond-containing side groups mainly includes the following route:
[0025] Synthesis of diamine-containing triaramine diomelamine:
[0026]
[0027] For diamondyl aniline and the contralated nitrobenzene, wherein the halogen atom may be chlorine, bromine, fluorine, preferably fluorine atom, dissolved in dimethyl permens in molar ratio 1: 2 to 2.1, at 110 ° C-150 The reaction was reacted at ° C for 12-16 h, and cesium fluoride as a catalyst was used, and the amount of the amount of the halogenated nitrobenzene material was used. After the reaction was completed, the mother liquor was poured into water, then filtered, washed, dried. The dinitrosyl compound was obtained, and then recrystallized using acetonitrile;
[0028] The dinitrosyl compound selects a palladium carbon catalytic reduction system to obtain a triarylamine diomide compound under hydrated hydrazine, and finally crystallization is perf...
Example Embodiment
[0035] Example 1
[0036] 0.1 mol of the diamondyl aniline and 0.21 mol of fluorine, dissolved in three flasks containing 100 ml of dimethyl sulfoxide and magnetic rotor, after dissolving, 0.16 mol of fluorine Curium, warmed to 120 ° C for 15 h. After the reaction was complete, the solution was poured into water, stirred rapidly, settled with 12 h, and filtered into a plurality of times and washed, dried to give a yellow solid crude product. Dinitrosyl compound was recrystallized using acetonitrile.
[0037] After the crystal dinitrosyl compound was 0.1 mol, and a thermometer containing 100 ml of ethanol was added to three bottles of the magnetic rotor, 10% palladium carbon was added, stirred well, slowly. The hydrated hydrazine was added to the reflux temperature, and the reaction was 12 h. After the reaction is complete, the palladium carbon is removed by heat-filming, and then pour it into the water to stir the precipitate, settled with 12h, washed multiple filtration, drying t...
Example Embodiment
[0039] Example 2
[0040] 0.5 mol of the diamondylphenylamine and 1.1 mol of chloronitrobenzene were dissolved in three bottles containing 500 ml of dimethyl sulfoxide with a thermometer and magnetic rotor, and 0.8 mol of fluorination was added. , Warmed to 150 ° C for 15 h. After the reaction was complete, the solution was poured into water, stirred rapidly, settled with 12 h, and filtered into a plurality of times and washed, dried to give a yellow solid crude product. Dinitrosyl compound was recrystallized using acetonitrile.
[0041]After the crystal, the dinitrosyl compound was obtained, and the thermometer containing 350 ml of ethanol was added to three bottles of the magnetic rotor, and 5% palladium carbon was added, stirred well, slowly Hydrate is warmed to the reflux temperature, and the reaction is 12h. After the reaction is complete, the palladium carbon is removed by heat-filming, and then pour it into the water and stirred the precipitate, settled with 12h, washed mul...
