Abstract A catalyst-free, three-component dearomatization of phenols with aryldiazonium tetrafluoroborates and DABCO·(SO2)2 has been developed for the synthesis 4-(arylsulfonyl)cyclohex-2,5-dien-1-one scaffolds. This method offers mild reaction conditions high step efficiency, providing a green efficient strategy phenols. Mechanistic studies indicated that this transformation relies on tandem radical sulfur dioxide insertion process.
