accounts for part of the THF-dG and THP-dG produced from the alpha-acetoxynitrosamines; stable oxonium ion-derived electrophiles may also be involved in the formation of THF-dG and THP-dG. Comparisons of the yields of various adducts in the reaction of alpha-acetoxyNPYR and alpha-acetoxyNPIP with dG showed some major differences. Whereas yields of THF-dG and THP-dG were similar, adducts formed from open chain

ridine are reported. The compounds differ in reactivity by more than 2 orders of magnitude at physiological pH. On the basis of thermodynamic parameters, common ion inhibition and azide ion trapping experiments, both compounds appear to decompose under these conditions by the formation of N-nitrosiminium ion intermediates. The differences in reactivity are rationalized on the basis of results from
