[摘要]：A study of the reaction of thioanisole with singlet oxygen in pyrrolidinium- and imidazolium-based ionic liqs. has been carried out. In these solvents, thioanisole shows a strongly enhanced reactivity with respect to mol. aprotic solvents, probably due to a stabilization of the persulfoxide intermediate in the ionic medium. Product isotope effects suggest a mechanistic change ongoing from pyrrolidinium to imidazolium solvents.
