    • It has been now surprisingly discovered after extensive research that 2-halo-4,6-bisaryl-1,3,5-triazine can be prepared with unprecedented selectivity, efficiency, mild conditions, and in high yield by the reaction of cyanuric halide with aromatics in the presence of at least one Lewis acid and at least one reaction promoter. This reaction is also unprecedently general as a variety of aromatics can be used to produce a wide selection of 2-halo-4,6-bisaryl-1,3,5-triazines. The novel approach includes the use of the reaction promoters in combination with at least one Lewis acid under certain reaction conditions to promote the formation of 2-halo-4,6-bisaryl-1,3,5-triazine compounds from cyanuric halide. Preferably, the Lewis acids and reaction promoter's are combined to form a complex 2-Halo-4,6-bisaryl-1,3,5-triazines are key intermediates for making 2-(2-oxyaryl)-4,6-bisaryl-1,3,5-triazine class of UV absorbers.
    • 现在已经广泛研究出人意料地发现,2-卤代-4,6-二芳基-1,3,5-三嗪可以以前所未有的选择性,效率,温和条件制备,并且通过氰尿酰卤与 芳族化合物在至少一种路易斯酸和至少一种反应促进剂的存在下进行。 该反应也是前所未有的,因为各种芳族化合物可用于产生广泛选择的2-卤代-4,6-二芳基-1,3,5-三嗪。 该新方法包括在某些反应条件下使用反应促进剂与至少一种路易斯酸组合以促进由氰尿酰卤形成2-卤代-4,6-二芳基-1,3,5-三嗪化合物。 优选将路易斯酸和反应促进剂组合以形成络合物2-卤代-4,6-二芳基-1,3,5-三嗪是制备2-(2-氧芳基)-4,6-二芳基-1,3,5-三嗪的关键中间体, 1,3,5-三嗪类紫外线吸收剂。
