| titleOfInvention | Method for catalyzing the addition reaction of alkyne and carbodiimide |
| abstract | The invention relates to a method for catalyzing the addition reaction of alkyne and carbodiimide, comprising the following steps: combining the alkyne represented by formula (1) and N,N'-diisopropyl represented by formula (2) Carbodiimide reacts under the catalysis of alkali metal salts in aprotic solvent dimethyl sulfoxide at 40-60 ° C; wherein, the structural formulas of formula (1) and formula (2) are as follows: Wherein, R is selected from aryl groups with 4-7 carbon atoms. The invention provides a method for effectively catalyzing the addition reaction of alkyne and carbodiimide to generate amidine compounds. The catalyst is simple and easy to obtain, easy to operate, mild reaction conditions and high yield. |
