摘要:
By means of pulse radiolysis in water, N-chlorosuccinimide (SCl) was reduced in a one-electron step to yield the succinimidyl radical, S., via the intermediacy of the radical anion, SCl.-. The rate of ring opening of S. was measured to be 8 x 10(4) s-1. By equilibration with Cl2.-/2Cl-, the one-electron reduction potential of S. was determined to be 2.22 +/- 0.02 V vs NHE. From this value and other data, the N-H bond strength in succinimide was calculated to be 118 +/- 3 kcal/mol.
