Using <i>N</i>‐Tosylhydrazone as a Double Nucleophile in the Palladium‐Catalyzed Cross‐Coupling Reaction To Synthesize Allylic Sulfones

Abstract

Without extra addition of sulfinate salt, allylic sulfones were synthesized by palladium-catalyzed cross-coupling of aryl iodide with N-tosylhydrazone. In this transformation, not only the diazo compound but also the sulfinate salt, which were both generated in situ from base-mediated decomposition of the N-tosylhydrazone, was used as nucleophilic partner.
