Enantioselective Alkoxycarbonyl‐Lactonization of Alkenes via the Merger of Photoredox and Copper Catalysis

Advanced Science, EarlyView.
A highly enantioselective alkoxycarbonyl‐lactonization of alkenes is reported through a photoredox/copper dual‐catalyzed alkoxycarbonyl radical addition/cyclization reaction. Abstract The synthesis of ester derivatives represents one of the most significant and fundamental tasks in modern organic chemistry, and numerous methods have been developed in ...

Direct Carboboration of Aryl Alkenes with Stable Organoborons Through Ziegler‐Type Addition

Advanced Science, EarlyView.
The direct carboboration of vinyl arenes with benzylic boronates has been achieved using KOtBu as the catalyst. Vinylcyclopropanes and vinylcyclobutane also participate in this reaction, yielding the corresponding 1,5‐ and 1,6‐carboboration products.

Enriched Oxygen Vacancy‐Mediated Efficient Charge Transfer in S‐Scheme ZnO‐VO@Zn0.5Cd0.5S Heterojunction for Rapid U(VI) Removal From Nuclear Wastewater

Advanced Science, EarlyView.
An S‐scheme ZnO‐VO@Zn0.5Cd0.5S heterojunction with oxygen vacancies (VO) was developed for rapidly removing U(VI) from nuclear wastewater. The results show that the synergy between S‐scheme transfer and VO enhances the catalyst’s U(VI) removal kinetics. It achieves 99.10% removal in 10 minutes without any sacrificial agents.
