| titleOfInvention | A method of utilizing alkene, amine, carbon dioxide and Togni reagent synthesis of carbamates |
| abstract | The present invention relates to a kind of methods using alkene, amine, carbon dioxide and Togni reagent synthesis of carbamates, this method is in a high pressure reaction kettle, to sequentially add organic solvent, alkene, amine, Togni reagent, and adding mantoquita is catalyst, carbon dioxide is then passed to, 40~100 o It is stirred to react under C 5~24 hours, is cooled to room temperature after reaction, slowly release carbon dioxide to normal pressure, reaction solution is extracted through washing, ethyl acetate, after anhydrous magnesium sulfate is dry, vacuum distillation is concentrated to get crude product, then obtains carbamate compound through column Chromatographic purification.The synthetic method of carbamate of the present invention avoids the raw material toxic using phosgene or isocyanates etc., safe operation is simple, reaction condition is mild, and functional group compatibility is good, substrate applicability is wide, yield is high, is conducive to industrial production, has a good application prospect in the synthesis of pesticide, medicine and natural products. |
