Abstract
Diaryliodonium triflates have been directly prepared by reaction of arenes with elemental iodine in good yields by using K2S2O8 and TFA, followed by treatment with NaOTf. This procedure avoids the use of high temperature and severe reaction conditions.
摘要
通过芳烃与单质碘在硫酸钾和三氟乙酸作用下反应，随后用三氟甲磺酸钠处理，可直接制备出高产率的三氟甲磺酸二芳基碘鎓盐。该方法避免了使用高温和苛刻的反应条件。
