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 0.39 g (0.5 eq) of aluminum hydroxide at ice-bath temperature. After 10 min of stirring, 1.9 eq of m-xylene was added. The cooling bath was removed after 10 min and the reaction mixture stirred at room temperature. HPLC analysis after 20 h at room temperature showed 98% 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 80:20.
