Visible light photoredox-catalyzed deoxygenation of alcohols
Carbon-oxygen single bonds are ubiquitous in natural products whereas efficient methods for their reductive defunctionalization are rare. In this work an environmentally benign protocol for the activation of carbon-oxygen single bonds of alcohols towards a reductive bond cleavage under visible light photocatalysis was developed. Alcohols were activated as 3,5-bis(trifluoromethyl)-substituted be...
متن کاملVisible light induced photocatalytic degradation of direct red 23 and direct brown 166 by InVO4-TiO2 nanocomposite
The effect of various parameters (pH, irradiation time, nanophotocatalyst dosages and temperature) on photocatalytic degradation of Direct Red 23 (DR 23) and Direct Brown 166 (DB 166) using pure InVO4 and InVO4-TiO2 nanocomposite were investigated under visible light irradiation. InVO4 and InVO4-TiO2 wer...

متن کاملDirect synthesis of α-bromoketones from alkylarenes by aerobic visible light photooxidation.
The direct synthesis of α-bromoketones from alkylarenes by aerobic photooxidation with hydrobromic acid is reported. The key success for this direct oxidative reaction is due to control of bromination with acetic acid and ethanol, which are generated in situ by solvolysis of ethyl acetate in the course of the reaction.
متن کاملReductive Umpolung of Carbonyl Derivatives with Visible‐Light Photoredox Catalysis: Direct Access to Vicinal Diamines and Amino Alcohols via α‐Amino Radicals and Ketyl Radicals
Visible-light-mediated photoredox-catalyzed aldimine-aniline and aldehyde-aniline couplings have been realized. The reductive single electron transfer (SET) umpolung of various carbonyl derivatives enabled the generation of intermediary ketyl and α-amino radical anions, which were utilized for the synthesis of unsymmetrically substituted 1,2-diamines and amino alcohols.
