| titleOfInvention | Preparation method of tetra-substituted sulfonated vinyl ether under electrocatalysis |
| abstract | The invention discloses an electro-catalysis method belonging to the technical field of organic synthesisA preparation method of tetra-substituted sulfonated vinyl ether. The method comprises the following steps: adding substituted alkyne, aryl sulfonyl hydrazide and tetraethyl ammonium hexafluorophosphate in a molar ratio of 1:3:1 into a reactor, adding an alcohol substance with the volume of 4.5mL, adding nitromethane as a solvent, and promoting the reaction by an electrocatalytic strategy. After the reaction is finished, concentrating by using a rotary evaporator to obtain a crude product, and separating by silica gel column chromatography to obtain the target product. The synthesis method of the tetra-substituted sulfonated vinyl ether compound provided by the invention is scientific and reasonable, the synthesis route is green and environment-friendly, and no metal catalyst is used; the reaction temperature is room temperature, and the reaction condition is mild; the reaction can take place under weak current; the synthetic method is simple and the reaction is rapid; the yield of the target compound is high, and the product is easy to purify. The reaction equation is as follows: |
