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 ...

Decoupling Electron and Proton Transfer in Noncontact Catalytic Hydrogenation of Nitroaromatics

Advanced Science, EarlyView.
A noncontact catalytic system is constructed by modifying metal nanoparticles supported on conductive carbon with (hypo)phosphorous acid. This design effectively prevents the adsorption of unsaturated substrates while permitting H2 activation to generate electrons and protons. The hydrogenation is governed by electron transfer processes, which occur at

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.

Inspired by Reinforced‐Concrete Structures: High‐Strength, Stable, Sustainable Reed‐Based Plastics

Advanced Science, EarlyView.
Inspired by the structure of reinforced concrete, which develops a composite with high‐strength, stability, fire resistance, and nontoxicity, by using the regular and continuous of reed fiber and thermoset tannin‐based resin. This composite demonstrates potential as a sustainable alternative to conventional petroleum‐derived plastics, with promising ...
