RESUMEN
Pulse-radiolysis experiments demonstrate that both the radical ion CIUra-/- and the protonated radical CIUraH- Of chlorouracil will transfer electrons to p-nitroacetophenone (PNAP). The reaction of CIUraH- is complicated by unknown reaction with PNAP below pH 4-4. Rate constants measured for reactions (2) and (3) are kappa2=5-3 x 109 and kappa3=3-3 x 109 M-1 sec -1. See article. An independent determination of the rate-constant for dissociation of the radical ion (equation (1)) was also obtained (kappa1=0-7 x 105 sec -1). See article.
