| titleOfInvention | Process for preparing triazines using a combination of lewis acids and reaction promoters |
| abstract | Surprisingly, after extensive studies, the invention of 2-halo-4,6-bisaryl-l, 3,5-triazines was performed with at least one Lewis acid and at least one reactive promoter in unexpected selectivity, efficiency, mild conditions and high yield. It has been found that it can be prepared by the reaction of a cyanuric halide with an aromatic in the presence of. This reaction can also be unexpectedly generally used to induce a wide variety of selectivity of 2-halo-4,6-bisaryl-1,3,5-triazines. The novel approach involves the use of a reaction promoter in combination with at least one Lewis acid under certain reaction conditions that promote the formation of a 2-halo-4,6-bisaryl-1,3,5-triazine compound from cyanuric halides. . Preferably, the Lewis acid and the reactive promoter are combined to form a complex. 2-halo-4,6-bisaryl-1,3,5-triazine produces a 2- (2-oxyaryl) -4,6-bisaryl-1,3,5-triazine class of UV absorbers It is the main intermediate. |
