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.

Advancing efficient and sustainable catalytic systems for organic transformation remains a pivotal objective in contemporary chemistry. This research introduces an innovative method employing visible light-driven quantum dots copper photocatalysis to achieve azide–alkyne cycloaddition (AAC) reactions at room temperature. The synergistic action of (QDs) catalysts under light exposure ensures high reaction efficiency regio-selectivity, offering ecofriendly energy-saving alternative conventional thermal approaches. In this study, CdS QDs play dual role: they act as electron donors, reducing Cu(II) Cu(I), enable rapid completion light, even without inert atmosphere or any sacrificial donor. use immiscible solvents allows easy separation, exhibit impressive properties. demonstrates turnover number (TON) 0.96 × 106 frequency (TOF) 0.16 h–1. Furthermore, work showcases broad substrate compatibility, tolerating various functional groups achieving excellent yields up 99% shorter time 6 h, thus establishing it versatile strategy synthesizing 1,2,3-triazoles. study underscores the potential merging QD with metal catalysis promote advancement chemical processes.
