2-(Trimethylsilyl)phenyl perfluorosulfonated aryne precursors may now be accessed using flow chemistry, enabling the fast preparation of pure compounds with no requirement for low temperature lithiation or column chromatography. The process has been adapted to novel nonaflate precursors, utilizing the cheaper and more user-friendly nonaflyl fluoride reagent. The resultant nonaflates are shown to successfully

A class of o-(trimethylsilyl)aryl fluorosulfates was synthesized by a concise method and successfully used as aryne precursors for the first time. Different trapping agents such as azides, furans, and acyl acetoacetates could successfully react with the aryne precursors under mild conditions with good to excellent yields.
