Regioselective installation of fluorosulfate (–OSO2F) functionality into aromatic C(sp2)–H bonds for the construction of para-amino-arylfluorosulfates

The construction of para-amino-arylfluorosulfates was achieved through installation of fluorosulfate (–OSO2F) functionality into aromatic C(sp2)–H bonds by the reaction of N-arylhydroxylamine with sulfuryl fluoride (SO2F2). This method provides a mild process for the preparation of broadly applicable fluorosulfate moieties without the requirement of phenols or transition metals.
