실험 절차

To a stirring mixture of 3.7 g (1 eq) of cyanuric chloride, 8 g (3 eq) of aluminum chloride in 50 mL chlorobenzene, was added 0.4 mL of aqueous sodium hydroxide solution (50%) at ice-bath temperature. After 10 min of stirring, 1.9 eq of m-xylene was added. The cooling bath was removed and the reaction mixture stirred at room temperature. HPLC analysis after 30 min at room temperature showed 91% of cyanuric chloride conversion to 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine, formed in a ratio of 96:4. A second sample analyzed after 1 h at room temperature showed 94% of cyanuric chloride conversion to 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2,4,6-tris(2,4-dimethylpheny)-1,3,5-triazine, in a ratio of 92:8. After a total of 4 h at room temperature, HPLC analysis showed 95% conversion of cyanuric chloride and a ratio of 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine to 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine of 89:11.
