(4-chlorophenyl)(diphenyl)sulfonium trifluoromethanesulfonate

Description:
(4-chlorophenyl)(diphenyl)sulfonium trifluoromethanesulfonate, identified by its CAS number 255056-43-0, is an organosulfonium compound that features a sulfonium cation and a trifluoromethanesulfonate anion. This compound is characterized by its sulfonium center, which is bonded to a 4-chlorophenyl group and two phenyl groups, contributing to its stability and reactivity. It is typically used as a photoinitiator in polymerization processes, particularly in UV-curable systems, due to its ability to generate reactive species upon exposure to light. The presence of the trifluoromethanesulfonate anion enhances its solubility in organic solvents and can influence its reactivity. Additionally, the chlorophenyl substituent may impart specific electronic properties, affecting the compound's behavior in chemical reactions. Overall, this substance is significant in materials science and organic synthesis, particularly in applications requiring controlled polymerization and cross-linking.
