摘要：

By means of pulse radiolysis N-bromosuccinimide, SBr, was reduced to its radical anion, SBr.-. Evidence is presented that SBr.- rapidly fragments into the succinimide anion, S-, and a free bromine atom, Br., which is converted into Br2.- by reacting with Br- present. The rate constant of hydrogen abstraction by Br. from 2-propanol and methanol have been determined. The carbon-centered radical of tert-butyl alcohol was also found to react with SBr yielding Br2.- in the presence of Br-.
