fluorine-containing groups, trifluoromethylarylethers (ArOCF3) have unique properties in drug design and are difficult to be synthesized, and many different methods were developed to prepare them. A novel one-pot synthesis of o-iodine-aryl trifluoromethylethers (ArOCF3I) was described by the reaction of trifluoromethoxylation and iodination with trifluoromethylaryl sulfonates (TFMS) in this manuscript
