Under the oxygen atmosphere conditions, PdCl₂/CuCl₂‐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.

通过Wacker氧化磺酰基邻烯丙基查耳酮一键访问磺酰基2-芳基萘

在氧气气氛条件下，PdCl ₂ / CuCl ₂介导的磺基邻烯丙基卤代烷的一锅Wacker型脱羧苯环化可在回流状态下在MeOH中提供磺酰基萘和羧酸。本文提出并讨论了一种合理的机制。这种高产率的方案通过一个碳-碳双键（C = C）的形成提供了一种高效的分子内闭环方法。
