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.

An electrochemical redox C(sp3)-H arylsulfonylation of xanthenes has been developed using aryl diazonium tetrafluoroborates and DABSO as the arylsulfone source. This radical reaction proceeds via formation arylsulfonyl radicals from between DABSO, followed by a cross-coupling process. Notably, occurs in absence any catalyst or external oxidant, providing efficient sulfonylation with broad functional group compatibility.
