Herein, we report a new method for the one-pot syntheses of sulfonyl fluorides. Addition of an alkyl, aryl, or heteroaryl Grignard to a solution of sulfuryl fluoride at ambient temperature affords the desired sulfonyl fluorides in 18-78% yield. Furthermore, this method is applicable for in situ sequential reactions, whereby the Grignard reagent can be converted to the corresponding diarylsulfone, sulfonate

A mild, efficientsynthesis of sulfonyl fluorides fromaryl and heteroaryl bromides utilizing palladium catalysis is described. The process involves the initial palladium-catalyzed sulfonylation of arylbromides using DABSO as an SO2 source, followed by in situ treatment of the resultant sulfinate with the electrophilic fluorine source NFSI. This sequence represents the first general method for the

A broad‐spectrum, catalytic method has been developed for the synthesis of sulfonamides and sulfamates. With the activation by the combination of a catalytic amount of 1‐hydroxybenzotriazole (HOBt) and silicon additives, amidations of sulfonyl fluorides and fluorosulfates proceeded smoothly and excellent yields were generally obtained (87–99 %). Noticeably, this protocol is particularly efficient for
