New aspects in the free-radical chemistry of pyrimidine nucleobases.


i) It has been known for some time that OH radicals and H atoms react with the pyrimidines by adding to the C(5)-C(6) double bond, but only the u.v.-spectra of the sum of these radicals have been reported so far. It will be shown how to arrive at the individual spectra of the C(5) and the C(6) adduct radicals. ii) alpha-Hydroxyalkyl radicals are known to… (More)
