Abstract:
This invention relates to a process for producing an amide compound by Beckmann rearrangement of an oxime compound using a compound having at least two electron-withdrawing leaving groups as a rearrangement catalyst, the process comprising a pre-preparation step in which the rearrangement catalyst and at least a part of the oxime compound are mixed and reacted; and a rearrangement reaction step in which the oxime compound is rearranged at a temperature higher than that in the pre-preparation step.
