Schematic Representation of Possible Mechanisms of the Base Catalyzed Aminolysis Reaction
General Base-Catalyzed Aminolysis.The next step in this
computational study is to investigate the catalytic effect of
methylamine and acetic acid for two considered mechanisms
for anhydride aminolysis.According to experimental observations,
the reaction can take place as a catalyzed process with
the catalytic involvement of the second amine molecule or
bifunctional catalysis with a carboxylic acid arising together
with the amide from the reaction between the anhydride and
the amine which manifests itself frequently in an S-shaped
transformation curve.29
From the results obtained for the base catalyzed aminolysis
reaction,one can see that the concerted mechanism as well as
the rate-determining step along the stepwise pathway involves
proton transfers through six-membered cyclic transition states

标题：碱催化的氨解反应几种可能反应机理的图示
关键词/摘要：一般的碱催化氨解反应.本数值计算研究的下一步工作将探讨
甲胺和乙酸对于两种无水氨解机理的催化作用.根据实验观测,该反应能以催化方式进行,其中第二个胺分子可参与催化作用,或在酐与胺反应过程中由一种羧酸与胺引发双功能催化机制,此一特征经常体现于其S-型转化曲线中.[29]
从获自碱催化氨解反应的观察结果可以发现,该协同反应机理及阶跃式反应途径中的限速步骤皆与六点周期性过渡态中的质子转移有关.
