The photochemical hydrogen abstraction reactions of flavone and its derivatives with some hydrogen donors in 2-propanol solutions were investigated at room temperture with the aid of a chemically induced dynamic electron polarization technique.When xanthene and N,N-diethylaniline were used as hydrogen donors, the ketyl redical of flavone was obtained through the n?* character and charge-transfer interaction of the triplet state, respectively.When tri-n-butyltin hydride and sodium borodeuteride were used as hydrogen donors, the benzyl-type radicals of flavones were obtained through the ??* character of the triplet states.
