Metal‐Free, Cooperative Asymmetric Organophotoredox Catalysis with Visible Light
TL;DR: The dawn of old stars: Classic xanthene dyes like eosin Y (gr. eoς=goddess of dawn) and green-light irradiation can replace precious metal complexes for the organocatalytic asymmetric -alkylation of aldehydes rendering the process purely organic.

Metal-free, cooperative asymmetric organophotoredox catalysis with visible light
TL;DR: The dawn of old stars: Classic xanthene dyes like eosin Y (gr. eoς=goddess of dawn) and green-light irradiation can replace precious metal complexes for the organocatalytic asymmetric -alkylation of aldehydes rendering the process purely organic as discussed by the authors.
Journal ArticleDOI
Visible-light-promoted stereoselective alkylation by combining heterogeneous photocatalysis with organocatalysis.
Maria Cherevatskaya,Matthias Neumann,Stefan Füldner,Christoph Harlander,Susanne Kümmel,Stephan Dankesreiter,Arno Pfitzner,Kirsten Zeitler,Burkhard König +8 more
TL;DR: Heterogeneous inorganic semiconductors and chiral organocatalysts team up for the stereoselective photocatalytic formation of carbon–carbon bonds and the connection between the organic and inorganic catalysts should not be too tight.
Journal ArticleDOI
Metallfreie kooperative asymmetrische Organophotoredoxkatalyse mit sichtbarem Licht
Journal ArticleDOI
Application of Microflow Conditions to Visible Light Photoredox Catalysis
Matthias Neumann,Kirsten Zeitler +1 more
TL;DR: The productivity of the synergistic, catalytic enantioselective photoredox α-alkylation of aldehydes was demonstrated to be increased by 2 orders of magnitude and the approach facilitates previously challenging transformations of nonstabilized intermediates.
