Photoredox-Enabled Chromium-Catalyzed Alkene Diacylations [PDF]
, 2022 Transition-metal-catalyzed cross-coupling reactions are a powerful tool to construct carbon–carbon bonds in modern synthetic chemistry. Chromium catalysis is much less developed compared with the widely used palladium and nickel catalysis.

Hydroxyl-Diazomethylation of Alkenes via Photoredox Catalysis [PDF]
, 2023 α-Diazoesters belong to significantly important carbenoid precursors in synthetic chemistry, diazomethylation-based difunctionalization of alkenes is highly valuable but remain nontrivial. Herein, we reported a general and modular approach for the direct

Organic synthesis using photoredox catalysis [PDF]
Beilstein Journal of Organic Chemistry, 2014 Natural photosynthesis is a remarkable chemical machinery that enables our life on earth and delivers a constant stream of oxygen and organic biomass. We should acknowledge this fact with humbleness, especially because we have not been able yet to mimic this process in a reliable way even after decades of intense research.
