실험 절차

To a stirring mixture of 1 eq of cyanuric chloride, 3.5 eq of AlCl3 in chlorobenzene, was added 0.036 eq of sulfuric acid as a 10% aq. solution at ice-bath temperature. After 10 min of stirring 1.9 eq of m-xylene was added. After 5 min at ice bath temperature the reaction mixture was allowed to warm to 10° C. After 1 h 20 min. HPLC analysis showed 89% of the cyanuric chloride had reacted to give 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine, which were present in a ratio of 89:11. HPLC analysis, after 3 h at 9-11° C., showed 94% of the cyanuric chloride had reacted to give 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine, which were present in a ratio of 95:5. HPLC analysis, after 5 h at 9-11° C. and 17 h at room temperature, showed 98.5% of the cyanuric chloride had reacted to give 2-chloro-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2,4,6-tris(2,4-dimethylphenyl)-1,3,5-triazine, which were present in a ratio of 97:3.
