The core of visible-light photoredox catalysis is that a photocatalyst absorbs visible light to form an excited state, which then drives redox cycles through single-electron transfer (SET) to generate highly reactive intermediates for bond construction and functional-group transformation under ...

Low-valent metal compounds are frequently employed as reducing agents. Given that its most stable oxidation state is 3+, indium is utilized in its 2+ oxidation state to function as a one-electron reducing agent.
The Stanford-based Du Bois group has refined the catalytic prowess of Rh in oxidative C-H activation reactions, targeting sulfamate, sulfamide, carbamate, urea, and guanidine substrates. This enhancement stems from their ingenious substitution of tetramethylated m-benzenediproprionic acid 1 ...
Aladdin Reagents Company is able to offer a range of BINOL-derived chiral phosphoric acids in its asymmetric catalyst/ligand product portfolio. This class of well-established chiral Brønsted acid catalysts has been increasingly used in efficient conversion reactions.
Recently, environmentally friendly oxidation reactions catalyzed by a nitrogen-oxygen radical, TEMPO, have attracted attention. Iwabuchi et al. reported that a nitrogen-oxygen radical, 2-azadamantane-N-oxygen (AZADO), efficiently catalyzed oxidation reaction of alcohols.
In recent years, asymmetric organic catalytic processes have increasingly become more mature and have been utilized in practical application scenarios.In comparison to metal catalytic processes, organic amine catalysts present numerous potential advantages, such as a more stable physicochemical ...
Since the first proline-catalyzed asymmetric synthesis was reported in 1971, a number of asymmetric syntheses using proline and derivatives have been developed. Proline-type organocatalysts are predominantly applicable to a wide assortment of asymmetric aldol reactions and asymmetric ...
C(sp2)- and C(sp)-hybridized coupling reactions are established catalytic approaches. However, multi-step C(sp3)- and C(sp2)-coupling reactions of boronic acids and related derivatives are still limited by ineffective two-electron transmetalation reactions. These conventional protocols exhibit ...
