실험 절차

To a stirring mixture of 1 eq of cyanuric chloride, 3 eq of AlCl3 in chlorobenzene, was added 0.24 eq of concentrated H2SO4 at ice-bath temperature. After 5 min of stirring 2 eq of m-xylene was added. After another 5 min, the cooling bath was removed and the reaction mixture was stirred at room temperature. HPLC analysis after 2 h at room temperature showed 100% 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 86:14.
