Cooperative flavin systems for organic photoredox catalysis

Flavins are redox-active compounds which effectively enter excited state upon irradiation with visible light. Importantly, they are photoactive both in oxidative and reductive form. Thus, in excited state, flavins are strong oxidizing or reducing agents which allow their participation both in oxidative and reductive part of the catalytic cycle. The aim of the work is to design catalytic systems with two cooperating flavin derivatives allowing new chemical transformations under mild conditions, for example C-H derivatization or C-C coupling. Work is focused on synthetic organic chemistry, nevertheless characterization of flavin catalysts by electrochemical or spectroscopic methods will be performed as well. Research will be performed in cooperation with other European universities.
