Under the oxygen atmosphere conditions, PdCl 2 /CuCl 2 ‐mediated one‐pot Wacker‐type decarboxylative benzannulation of sulfonyl o ‐allylchalcones provides sulfonyl naphthalenes and carboxylic acids in MeOH at reflux. A plausible mechanism is proposed and discussed herein. This high‐yield protocol provides a highly effective intramolecular ring‐closure via one carbon‐carbon double bond (C=C) formation.
