The hydrolysis of benzaldehyde acetal 3, catalysed by the neighbouring carboxy group, is some 105 times faster than that of a comparable system 6, which does not form a strong intramolecular hydrogen bond in the transition state for the reaction.
在邻近羧基的催化下,苯甲醛缩醛 3 的水解速度比类似体系 6 快约 105 倍,后者在反应的过渡态下不会形成强的分子内氢键。
