| titleOfInvention | Ultrasonic-assisted method for synthesizing Z-2-halogenated-1-thiocyanatoethylene compound |
| abstract | The invention discloses a method for synthesizing a Z-2-halogenated-1-thiocyanato ethylene compound under the assistance of ultrasonic waves. Under the synergistic action of ultrasonic wave and mechanical stirring, the sulfonic acid ionic liquid catalyzes 1-halogenated alkyne, potassium thiocyanate and water to perform three-component selective addition reaction, and the Z-2-halogenated-1-thiocyanato ethylene compound is efficiently synthesized under the solvent-free condition. The method has the advantages of easily obtained raw materials, simple and convenient reaction conditions, mildness, greenness, energy conservation, high reaction selectivity and yield, excellent substrate functional group compatibility and higher application value. |
