| titleOfInvention | Coumarin thiocarbazone derivative, preparation method and application thereof |
| abstract | The invention relates to a coumarin thiocarbazone derivative, a preparation method and application thereof, and belongs to the technical field of organic synthesis. The preparation method of the coumarin thiocarbazone derivative comprises the following steps: S1: adding 3-acetyl-7-diethylamino coumarin in an organic solvent to dissolve, then adding thiocarbazide to obtain a mixture S2: carry out reflux stirring reaction with S1 gained mixture under normal pressure; S3: after reaction finishes, be cooled to room temperature, have solid precipitation, filter under reduced pressure, get filter residue; S4: S3 gained filter residue is washed, obtain coumarin Thiocarbazone derivatives. The coumarin thiocarbazone derivative has high sensitivity and strong selectivity when used as a fluorescent probe to detect zinc ions and copper ions. |
