Sulfur(VI) fluorideexchange (SuFEx) click chemistry provides a powerful tool for the rapid assembly of modular connections. Herein, we report an organocatalytic SuFEx reaction of sulfonyl fluorides, fluorosulfates, and sulfamoyl fluorides. Under the catalysis of 10 mol % N-heterocyclic carbene (NHC), or under the relay catalysis of NHC and HOBt, different SuFExable hubs efficiently undergo click reactions
Sulfonamides have been identified as by-products in the base-mediated transesterification of N-unsubstituted carbamates with sulfonyl chlorides to give the corresponding sulfonates. A proposed mechanism and the synthesis of hindered 2,6-disubstituted arylsulfonates via this method are also reported. (C) 2003 Elsevier Ltd. All rights reserved.
