Sonolysis, radiolysis, and hydrogen peroxide photolysis of pyrimidine derivatives in aqueous solutions: a spin-trapping study.


The sonolysis of aqueous solutions of various dihydropyrimidines and substituted pyrimidines was investigated by ESR and spin trapping with the nonvolatile, water soluble spin trap, 3,5-dibromonitrosobenzene sulfonate (DBNBS) and its deuterated analog to examine the possibility of detecting new radicals specifically generated in the high temperature zones… (More)
