late-stage radiosynthesis, 6 the synthesis of fluorogenic probes 7 and so on. As a result, the development of new method for the synthesis of aryl fluorosulfates is highly significant. Unfortunately, there was no applicable method for the preparation of these important organosulfur compounds for a long time. Early developed synthetic methods, such as the pyrolysis of arenediazonium fluorosulfate salts, the reaction of phenols with ClSO2F or fluorosulfonic acid anhydride 10 usually suffer from risky conditions, costly starting materials and low reaction yield. In 2014, Sharpless and coworkers launched Sulfur (VI) -Fluoride Exchange (SuFEx) click chemistry. This new embodiment of click chemistry provides a powerful and robust tool for modular assembly of various sulfonylated compounds. In particular, Sharpless and coworkers recognized the gaseous SO2F2 as an valuable SuFExable hub. In the presence of excess of base, SO2F2 can react with phenols to give aryl fluorosulfates in excellent yields. Interestingly, using aryl silyl ethers instead of phenols, catalytic amounts of DBU can catalyze the reaction in quantitatively yields. Recently, Moses and coworkers reported an interesting accelerated SuFEx click chemistry for quick synthesis of various sulfonylated compounds. They reported that in the presence of 1.0 equivalent of hexamethyldisilazane (HMDS), catalytic amount of Barton's base BTMG can catalyze the heterogeneous SuFEx click reaction of phenols and SO2F2 to give aryl fluorosulfates in high yields within 15 min. Despite progress made in this research, no general and catalytic silicon-free for SuFEx of SO2F2 has been disclosed.
