摘要：

Anchoring riboflavin tetraacetate to mesoporous silica (MCM-41) provides a heterogenized flavin photocatalyst, which was proven to be an effective catalyst for chemoselective sulfoxidation, benzyl alcohol oxidation, and photoesterification reactions. Analogously heterogenized 1-butyl-7,8-dimethoxyalloxazine was shown to mediate sulfoxidation and benzylic oxidation reactions. This is the first application of an alloxazine photocatalyst in a redox reaction. The use of these heterogeneous catalysts allows simple operation and work-up of the reaction mixtures. [GRAPHICS] .
