The photochemical hydrogen abstraction reactions of flavone and its derivatives with some hydrogen donors in 2-propanol solutions were investigated at room temperature with the aid of a chemically induced dynamic electron polarization technique. When xanthene and N,N-diethylaniline were used as hydrogen donors, the ketyl radical of flavone was obtained through the n..pi..* 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 ..pi pi..* character of the triplet states.
