| titleOfInvention | Synthesis method of 2-nitroethenyl thiophene |
| abstract | The invention relates to a synthesis method of 2-nitroethenyl thiophene. The synthesis method comprises the following steps: adding 2-thiophenecarboxaldehyde, nitromethane, beta-alanine dissolved with acetonitrile and a solvent into a reaction flask, reacting for 1h under unltrasound irradiation; after reaction, removing acetonitrile, filtering out beta-alanine, concentrating, and recrystallizing residues to obtain 2-nitroethenyl thiophene. The synthesis method provided by the invention has the characteristics of low cost, simpleness and convenience in operation, high yield and the like, and is suitable for industrial production. |
