摘要：

The electroreduction of secondary 2-bromoisobutyramides in dipolar aprotic solvent affords carbanions in an overall two electron process. The fast proton transfer between the electrogenerated base and the NH acid starting material (self-protonation) has been studied by cyclic voltammetry at the mercury electrode. Measurements of the second-order rate constant of the self-protonation step have been performed at 0°C for a series of ten bromoamides. The results are discussed on the basis of the effect of the substituent at nitrogen on the acid-base properties of both α-carbon and nitrogen atoms. © 1990.
