The ambiphilic reactivity of alkyl sulfonyl fluorides in stereoselective cyclopropanation under Pd(II) catalysis is reported. The method provides convenient access to cis-disubstituted cyclopropanes that are otherwise challenging to access. A representative carboxylic acid cyclopropane building block is scaled up to 100 mmol, demonstrating the practicality of this transformation.
