The return of the succinimidyl radical

The aqueous kinetics of the succinimidyl radical, S., has been re-examined in the presence of oxidizable substrates and oxygen. The results indicate a rapid equilibrium between S. and its ring-opened analogue, the β-(isocyanato-carbonyl)ethyl radical, PI.. The equilibrium constant K1 is ca. 10, with k1 ≈ 107 s-1 and k-1 ≈ 106 s-1. The glutarimidyl radical, G., was produced by one-electron reduction of N-chloroglutarimide, GCl. The rate constants of several oxidation and hydrogen abstraction reactions with S. and G. have been determined. Furthermore, halogen abstraction reactions from haloimides by some selected alkyl radicals were also scrutinised. Most striking is the finding that the 2-cyanoethyl radical abstracts Br from SBr ca. 25 times slower than does the ethyl radical. This demonstrates a strong β-effect and rationalises a relatively slow Br abstraction rate by PI. from SBr. While the closure rate of the PI' radical appears to be solvent-insensitive, the ring opening rate of S., k1, is estimated to be ca. 100 times faster in, e.g., CH2Cl2 than in water. This suggests hydrogen-bonded stabilisation of S.. Acta Chemica Scandinavica 1998.
