| titleOfInvention | Synthesis method of end-group alkyne |
| abstract | The invention relates to a synthesis method of end-group alkyne, which comprises the steps of: mixing solvent and lithium acetylide ethylenediamine; cooling the solution to -10 to 10 DEG C when the solution is clear, and then adding haloalkane into the cooled solution; leading the molar ratio between the lithium acetylide ethylenediamine and the haloalkane to be 1: 1-2: 1, and controlling the temperature to be -20 to 20 DEG C and the reaction time to be 0.5-5h; and finally, extracting, washing, distilling, collecting fraction with the boiling point close to that of the product, and obtaining a finished product. Compared with the prior art, the synthesis method has the advantages of simple method, convenient operation, high yield and the like. |
