| titleOfInvention | A kind of copper salt catalyzed method for preparing N-vinylamide compounds |
| abstract | The invention discloses a method for preparing N-vinylamide compounds catalyzed by copper salts. The method comprises the following steps: in an airtight container under the protection of an inert gas, amide, vinyl alkyl ether, and a copper salt catalyst Under the condition of an organic solvent, react at 95-105°C for 4-10 hours; after the reaction, the reaction liquid is cooled to room temperature, and the N-vinylamide compound is obtained through separation and purification; the copper salt catalyst is anhydrous A complex of copper sulfate or anhydrous copper sulfate and 8-hydroxyquinoline in a substance amount of 2 to 1:1; the substance ratio of the amide, vinyl alkyl ether, and copper salt catalyst is 20:100 to 200 : 2～1. The present invention uses a simple copper salt as a catalyst. Compared with the existing methods, the catalyst is cheap and easy to obtain, the reaction is free of halogen introduction, and it is environmentally friendly. The reaction does not need to add additives such as acid and alkali, and the system is simple. The present invention provides an effective method for preparing N ‑Vinyl amides method. |
