H. Kawata et al., PHOTOREDUCTION OF FLAVONE - IDENTIFICATION OF THE PHOTOPRODUCTS AND REACTION-MECHANISM, Journal of photochemistry and photobiology. A, Chemistry, 101(2-3), 1996, pp. 201-204
The photoreduction of flavone was investigated in 2-propanol or in ben
zene containing N,N-dimethylaniline by a continuous light irradiation
(lambda = 300 nm), a flash photolysis and CIDEP methods. The photoreac
tion proceeds via the triplet state of flavone and gives the dimers of
flavanon in 2-propanol, the diastereoisomers, which are different fro
m the pinacol-type dimer.
