Pokluda, Adam published the artcileRobust Photocatalytic Method Using Ethylene-Bridged Flavinium Salts for the Aerobic Oxidation of Unactivated Benzylic Substrates, Formula: C2H6N2O, the main research area is ethylene bridged flavinium salt photoredox catalyst preparation fluorescence; benzyl ethylene bridged flavinium salt photocatalyst aerobic oxidation; aryl ketone preparation.
A series of ethylene-bridged flavinium salts I (R1, R2 = H, OMe, CF3, Cl; R1R2 = OCH2O; R3 = H, Me, n-octyl) has been synthesized and their photochem. and electrochem. properties have been studied. Out of these compounds, 7,8-dimethoxy-3-methyl-1,10-ethylenealloxazinium chloride I [R1 = R2 = MeO; R3 = Me; (II)] was found to be a superior photooxidation catalyst. The flavinium salt II proved to be robust enough for practical applications in benzylic oxidations/oxygenations, which was demonstrated using a series of substrates with high oxidation potential, i.e., 1-phenylethanol, ethylbenzene, diphenylmethane and diphenylmethanol derivatives substituted with electron-withdrawing groups (Cl or CF3). The unique capabilities of the compound II can be attributed to its high photostability and participation via a relatively long-lived singlet excited state, which was confirmed using spectroscopic studies, electrochem. measurements and TD-DFT calculations This allows the maximum use of the oxidation power of the compound II, which was given by its singlet excited state reduction potential of +2.4 V. This compound can be used as an alternative photocatalyst for even more difficult substrates.
