Highly cited papers
Article (Org. Lett. 2019, 21, 114-119) published by our group in cooperation with the group of prof. Roithová met the criteria of web of science for "Highly cited papers“ (As of November/December 2019, this paper received enough citations to place it in the top 1% of the academic field of Chemistry based on a highly cited threshold for the field and publication year).
We report a system with ethylene-bridged flavinium salt 2b which catalyzes the aerobic oxidation of toluenes and benzyl alcohols with high oxidation potential (Eox > +2.5 V vs SCE) to give the corresponding benzoic acids under visible light irradiation. This is caused by the high oxidizing power of excited 2b (E(2b*) = +2.67 V vs SCE) involved in photooxidation and by the accompanying dark organocatalytic oxygenation provided by the in situ formed flavin hydroperoxide 2b-OOH.
