Fluorinated organic compounds are playing an increasingly vital role in pharmaceuticals, agrochemicals, and materials science. With superior metabolic stability, moderate lipophilicity, and unique electronic effects, the trifluoromethoxy (OCF₃) group is a highly valued structural motif. In recent years, a variety of innovative synthetic strategies have been developed for the efficient construction of OCF₃-containing organic molecules. Tangʼs group has long been dedicated to the development of novel trifluoromethoxylation reagents and methodologies. The recent progress of Tangʼs group in the field of trifluoromethoxylation reactions achieved between 2021 and 2026 is summarized, with a particular focus on the application of these methods in the synthesis of functional molecules.

Key words: trifluoromethoxylation, trifluoromethyl aryl sulfonate (TFMS), bifunctional N-OCF₃ reagent
