Abstract:
1. A process for synthesizing a trisaryl triazine compound comprising reacting a cyanuric halide of Formula V: where each X is independently a halide such as fluorine, chlorine, bromine or iodine, with a compound of Formula II: wherein R 6 , R 7 , R 8 , R 9 , and R 10 are the same or different and each is hydrogen, halogen, alkyl of 1 to 24 carbon atoms, haloalkyl of 1 to 24 carbon atoms, aryl of 6 to 24 carbon atoms, alkenyl of 2 to 24 carbon atoms, acyl of 1 to 24 carbon atoms, aralkyl of 7 to 24 carbon atoms, aracyl of 6 to 24 carbon atoms, OR, NRR′, CONRR′, OCOR, CN, SR, SO 2 R, SO 3 H, SO 3 M, wherein M is an alkali metal, R and R 1 are the same or different and each is hydrogen, alkyl of 1 to 24 carbon atoms, haloalkyl of 1 to 24 carbon atoms, aryl of 6 to 24 carbon atoms, alkenyl of 2 to 24 carbon atoms, acyl of 1 to 24 carbon atoms, cycloalkyl of 1 to 24 carbon atoms, cycloacyl of 5 to 24 carbon atoms, aralkyl of 7 to 24 carbon atoms, or aracyl of 6 to 24 carbons atoms, and optionally with either of R 6 and R 7 , R 7 and R 8 , R 8 and R 9 , or R 9 and R 10 , taken together being a part of a saturated or unsaturated fused carbocyclic ring optionally containing O, N, or S atoms in the ring, in the presence of at least one solvent and a reaction facilitator comprising at least one Lewis acid and at least one reaction promoter, for a sufficient time, at a suitable temperature and pressure to form the trisaryl triazine compound, with the proviso that the reaction promoter is different than the compound of Formula II.
