Abstract

The resins with 5-deazaflavin group attached to polystyrene via methylene linkage were prepared by condensation of the corresponding 10-alkyl-5-deazaflavins with chloromethyl- polystyrene. These resins oxidized benzyl alcohol under alkaline conditions to yield benzaldehyde in the same way as 5-deazaflavins themselves.
