Kinetic investigation of the acid hydrolysis of N-(methoxyprop-2-yl)benzanilide (1) was performed in 8.84 M HCl and/or DCl at 75.1°C. The formation of 2-(N-phenylamino)propanol (4) was explained and the mechanism, involving an initial ether cleavage anchimerically assisted by the amide group, was clarified. The overall process evolves through three steps involving two intermediates. The rate constants
N-(甲氧基丙-2-基)苯甲腈(1)的酸水解动力学研究是在75.1°C的8.84 M HCl和/或DCl中进行的。对2-(N-苯基氨基)丙醇(4)的形成进行了解释,并阐明了由酰胺基团辅助通过胺基异构体进行的初始醚裂解的机理。整个过程通过涉及两个中间体的三个步骤发展。各个过程的速率常数已通过UV和1 H NMR光谱技术确定。
