摘要

Abstract Elimination reactions of (1a-e) promoted by in 70 mol% MeCN (aq) have been studied kinetically. The reactions are second-order and exhibit Br nsted= 0.80-0.84 and= 0.39-0.42, respectively. For all leaving groups and bases employed in this study, the and values remained almost the same. The results can be described by a negligible interaction coefficient,, which describes the interaction between the base catalyst and the leaving ...
