Aggregation effects in visible light flavin photocatalysts: Synthesis, structure and catalytic activity of 10-arylflavins

Original language description

A series of 10-arylflavins (10-phenyl- (2a), 10-(2,6-dimethylphenyl)- (2b), 10-(2,6-diethylphenyl)- (2c), 10-(2,6-diisopropylphenyl)- (2d), 10-(2-tert-butylphenyl)- (2e), and 10-(2,6-dimethylphenyl)-3-methyl- (2f) isoalloxazine) was prepared as potentially non-aggregating flavin photocatalysts. The investigation of their structures in the crystalline phase combined with 1H-DOSY NMR experiments in CD3CN, CD3CN/D2O 1:1 and in D2O confirm reduced ability of 10-arylflavins 2 to form aggregates in comparisonwith tetra-O-acetyl riboflavin (1). 10-Arylflavins 2a-2d do not interact by interactions, which are restricted by 10-phenyl ring oriented perpendicularly to the isoalloxazine skeleton. On the other hand, N(3)-H---O hydrogen bonds have been detected in their crystal structures. In the structure of 10-aryl-3-methylflavin (2f) with substituted N(3) position, weak C-H---O bonds and weak interactions have been found. 10-Arylflavins 2 were tested as photoredox catalysts for the aerial oxidati
