Embodiment 1
[0185]
[0186] Under a nitrogen protective atmosphere, in a 250ml four-necked flask equipped with a stirrer, a thermometer, a condenser and a water separator, add 31.26 grams (116mmol) of octadecylamine and 6.36 grams (212mmol) of paraformaldehyde, 9.05 grams (76mmol) Benzotriazole and 25.41 g (105 mmol) of di-n-butyldithiophosphoric acid were stirred rapidly, and the temperature was raised to 100° C. for 3 h. After the reaction was completed, the remaining water was distilled off under reduced pressure, cooled to room temperature, settled for 24 hours, filtered to remove impurities, and separated by column chromatography to obtain the final product, marked as M-1.
[0187] Product characterization data are as follows:
[0188] 1 H NMR (300MHz, CDCl 3 ): δ0.88(3H), 1.03-1.71(46H), 2.61-3.93(6H), 4.22-4.54(2H), 5.20-6.15(2H), 7.18-8.08(4H);
[0189] C 34 h 63 N 4 o 2 P.S. 2 Calculated for C 62.35, H 9.70, N 8.55, O 4.89, P 4.73, S 9.79; found: C 63.25, H 10.0, N 8.4...

[0191]
[0192] Under a nitrogen protective atmosphere, in a 500ml four-necked flask equipped with a stirrer, a thermometer, a condenser and a water separator, add 60.10 grams (223 mmol) of octadecylamine and 18.3 grams (610 mmol) of paraformaldehyde and 30.60 grams (230 mmol) 5-Methylbenzotriazole was stirred rapidly, the temperature was raised to 85°C, 71.31 g (251 mmol) of isopropyl 2-ethylhexyl dithiophosphoric acid was added dropwise, and the reaction was carried out at constant temperature for 6 hours. After the reaction was completed, the remaining water was distilled off under reduced pressure, cooled to room temperature, settled for 24 hours, filtered to remove impurities, and separated by column chromatography to obtain the final product, marked as M-2.
[0193] Product characterization data are as follows:
[0194] 1 H NMR (300MHz, CDCl 3 ): δ0.88(9H), 1.08-1.71(47H), 2.43-3.93(7H), 4.22-4.54(2H), 4.74(1H), 5.20-6.21(2H), 7.39-7.75(3H);

Embodiment 3
[0197]
[0198] Under nitrogen protection atmosphere, in the 500ml four-neck flask that stirrer, thermometer, condenser and water separator are equipped with, add 25.9 grams (130mmol) tertiary carbon primary amines and 13.5 grams (450mmol) paraformaldehyde, 21.89 grams (125mmol) ) 6-butylbenzotriazole and 100mL toluene, stirred rapidly, raised the temperature to 95°C, added 55.23g (150mmol) bis(2-ethylhexyl)dithiophosphoric acid dropwise, and reacted at constant temperature for 5h. After the reaction was completed, the solvent and residual water were distilled off under reduced pressure, cooled to room temperature, settled for 24 hours, filtered to remove impurities, and separated by column chromatography to obtain the final product, marked as M-3.
[0199] Product characterization data are as follows:
[0200] 1 H NMR (300MHz, CDCl 3 ): δ0.89(18H), 1.05-1.93(48H), 2.34-2.50(2H), 3.43-3.72(4H), 4.24-4.72(2H), 5.31-6.20(2H), 7.19-7.82(3H) ;
