A nonlinear Hammett relationship could be used as evidence for a change-over in mechanism in the alkaline hydrolysis of methyl carbanilates. The electron-withdrawing substituted compounds hydrolyse via an A–E pathway (ϱ 1.06) whereas the hydrolysis of the electron-donating substituted compounds involves an E-A scheme.
非线性的Hammett关系可以用作证据证明氨基甲酸甲酯的碱水解机理发生了变化。吸电子取代的化合物通过A–E途径水解(ϱ 1.06),而给电子取代的化合物的水解则涉及EA方案。
