- 論文の詳細を見る
With cinnamic acid in aqueous methanol <I>N</I>-bromosuccinimide yields 2-bromo-3-methoxy-3-phenylpropionic acid. It is a second-order reaction independent of [H<SUP>+</SUP>] at moderately high [H<SUP>+</SUP>]. At low [H<SUP>+</SUP>] the rate increases with decrease in [H<SUP>+</SUP>]. The reaction is inhibited by succinimide. The reaction rate decreases with increase in methanol content of the medium. Mechanistic pathways of the reaction are discussed and a rate equation is derived.
