Abstract
A mild and efficient method for deoxygenative C2-sulfonylation of quinoline N-Oxides in the presence of a base has been developed employing extremely inexpensive SO2F2 as an activator and sodium sulfinate as nucleophilic sulfonylation source. It is noteworthy that the reaction proceeded well under metal- and oxidant-free conditions to give a variety of 2-sulfonylquinolines in medium to good yields.
