Ptasinska, Sylwia published the artcileBond- and Site-Selective Loss of H– from Pyrimidine Bases, Application In Synthesis of 608-34-4, the publication is Physical Review Letters (2005), 95(9), 093201/1-093201/4, database is CAplus and MEDLINE.
Electron attachment to gas phase thymine and uracil leads to H– loss within a broad and structured feature in the energy range between about 5 and 12 eV consisting of 4 overlapping resonances. By using thymine and uracil methylated at the N1 and N3 positions, resp., and taking into account recent results from partly deuterated thymine, we find that by tuning the electron energy, H– loss turns out to be not only bond selective, i.e., (C-H) vs. (N-H) bonds, but also site selective (N1 vs. N3 site). Such a bond and site selectivity by energy has not been observed before in dissociative electron attachment. Implications for the mechanism of strand breaks observed in plasmid DNA are considered.
