Abstract: 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 promoters 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.

Abstract: The invention relates to a novel process for making 2-(2-hydroxy-4-alkoxyphenyl)-4,6-bisaryl-1,3,5-triazine and 2-(2,4-dialkoxyphenyl)-4,6-bisaryl-1,3,5-triazine compounds directly from 2-chloro-4,6-bisaryl-1,3,5-triazine compounds with 3-alkoxyphenol, 1,3-dialkoxylbenzene compounds or mixtures thereof. The reaction step to prepare 2-chloro-4,6-bisaryl-1,3,5-triazines from the reaction of cyanuric chloride with substituted aromatic compounds can be combined with the addition reaction of 3-alkoxyphenol or 1,3-dialkoxylbenzene in a two-step, one-pot process. The 2-(2-hydroxyl-4-alkoxyphenyl)-4,6-bisaryl-1,3,5-triazine, and 2-(2,4-dialkoxyphenyl)-4,6-bisaryl-1,3,5-triazine compounds, are useful to stabilize materials against damage by light, heat, and oxygen, and as stabilizers for organic material, or mixtures thereof.
