Rates of reaction of seven N,N-dialkylformamide acetals R12N–CH(OR2)2 with a series of anilines substituted on the phenyl ring have been measured in benzene, methanol, chloroform, and tetrahydrofuran by use of a g.l.c. method. In each case studied reaction is irreversible and obeys a second-order kinetic equation. Reaction rates correlate with Hammett σ constants for substituents on the phenyl ring
使用glc方法测定了苯,甲醇,氯仿和四氢呋喃中七个N,N-二烷基甲酰胺缩醛R 1 2 N–CH(OR 2)2与在苯环上取代的一系列苯胺的反应速率。。在每种情况下,研究的反应都是不可逆的,并且服从二阶动力学方程。反应速率与苯胺分子苯环上取代基的Hammettσ常数相关。在动力学数据的基础上,讨论了反应机理。
