The present invention relates to a preparation method of N-formamide compounds. The method is as follows: using halides and formamide as raw materials, heating and reflux reaction in the presence of a solvent or no solvent and an acid-binding agent and a catalyst or no catalyst. ~10h, after the reaction is finished, the reaction solution is subjected to post-treatment such as extraction to obtain N-formamide compounds; the ratio of the amount of the halogenated product to the formamide is 1:1-100, and the reaction is preferably performed under solvent-free conditions. The preparation method of the invention has the advantages of high yield, convenient aftertreatment, cheap catalyst, simple operation, mild conditions, easy reaction control, less generation of three wastes, low risk, etc., and is suitable for industrial production. |
