[0038] According to the present disclosure, the preparation method of the intermediate compound represented by formula (14) may comprise: under the conditions of dehydration reaction, contacting the compound represented by formula (15) with the compound represented by formula (16);
[0039]
[0040] Among them, R 1 It can be an alkyl group with 1-10 carbon atoms, a haloalkyl group with 1-10 carbon atoms, or a substituted or unsubstituted aryl group with 6-10 carbon atoms, and the substituent in the substituted aryl group is Alkyl groups with 1-5 carbon atoms;
[0041]In order to improve the reaction conversion rate, preferably, the molar ratio of the compound shown in the formula (15) to the compound shown in the formula (16) can be 1:(0.5-2), more preferably 1:(0.7-1.5 ); the reaction conditions of the dehydration reaction may be: the reaction temperature is 0-60°C, the reaction time is 0.5-3h, and the more preferred reaction conditions may be: the reaction temperature is...
Embodiment 1
[0055] This example is used to illustrate the preparation method of the polyfunctional monomer compound of the present disclosure.
[0056] 1. Prepare medicines: trifluoromethanesulfonic acid and dimethyl dihydroxy silicon (molar ratio 2:1), some dehydrating agents. Use a flask as a reaction vessel, the reaction temperature is 30°C, in the presence of dehydrating agent titanium tetrachloride, slowly drop trifluoromethanesulfonic acid into dimethyl dihydroxy silicon, continue the reaction for 1 hour after the drop is completed, and then cool to room temperature Take out to obtain intermediate compound C1;
[0057] 2. Add dipentaerythritol pentaacrylate dropwise to intermediate compound C1, control the molar ratio of intermediate compound C1 and dipentaerythritol pentaacrylate to 1:1, and add a dehydrating agent to the system at the same time. Use a flask as a reaction vessel, the reaction temperature is 60°C, continue the reaction for 1 hour after the dropwise addition is comp...
Embodiment 2
[0061] Using the method of Example 1, the difference is that trifluoromethanesulfonic acid is replaced by an equivalent amount of benzenesulfonic acid to obtain the multifunctional monomer compound A2 of this example (yield 82%; 1 H NMR (400MHz, CDCl 3 , ppm), δ=7.62-7.86 (5H, t), 0.14 (6H, s), 3.71-4.07 (16H, t), 5.59-6.27 (15H, t)).
