Embodiment 1
[0026] Example 1: Synthesis of compound 001, the specific preparation steps are as follows:
[0027] Step (1) Put 4.80g K 2 CO 3 (34.8mmol), 5.00g of p-bromophenol (29.0mmol) and 50mL of dry THF solution were added to a two-necked flask to form a white suspension. Stir at a constant temperature of 70°C for 1 hour. When the suspension becomes clear, drop 1.00g A dilute THF solution of hexachlorocyclotriphosphazene (2.90 mmol) was reacted at 70° C. for 48 hours. A white solid appeared to stop the reaction. The reaction liquid was filtered, the solid was filtered off, the filtrate was taken, and then extracted with saturated NaCl solution 3 times, with anhydrous MgSO 4 The organic layer was dried, filtered and evaporated, washed twice with methanol, and filtered and dried to obtain 3.14 g of the intermediate product with a yield of 92.7%.
[0028] Step (2) 1.170g of the above intermediate product (1.00mmol) prepared in step (1), 2M K 2 CO 3 The solution is 5mL, containing 2.00g anthra...
Embodiment 2
[0032] Example 2: Synthesis of compound 002, the specific preparation steps are as follows:
[0033] Step (1) Put 4.80g K 2 CO 3 (34.8mmol), 5.00g of tribromophenol (29.0mmol) and 50mL of dry THF were added to a two-necked flask to form a white suspension. Stir at a constant temperature of 70°C for 1 hour. When the suspension becomes clear, add 1.00g of six The dilute THF solution of chlorocyclotriphosphazene (2.90 mmol) was added to the clear liquid, and the reaction was kept at 70°C for 48 hours. The reaction was stopped when a white solid appeared. The reaction liquid was filtered, the solid was filtered off, the filtrate was taken, and then extracted with saturated NaCl solution 3 times, with anhydrous MgSO 4 The organic layer was dried, filtered and evaporated, washed twice with methanol, and filtered and dried to obtain 3.30 g of intermediate product 2, with a yield of 96.0%.
[0034] Step (2) 1.170g of the above intermediate product (1.00mmol) prepared in step (1), 2M K 2 CO...
