| titleOfInvention | Synthesis method of 1- (9-carbazolyl) -2-phenyl-1, 2-ethanedione derivative |
| abstract | The invention aims to overcome the defects of the existing synthesis technology of carbazolyl-1, 2-ethanedione derivatives, provides a synthesis method of 1- (9-carbazolyl) -2-phenyl-1, 2-ethanedione derivatives, and belongs to the technical field of organic compound synthesis. The process employs a copper catalyst with R 1 -substituted carbazoles (II) with R 2 The 1- (9-carbazolyl) -2-phenyl-1, 2-ethanedione derivative is directly prepared from substituted benzoyl formaldehyde hydrate (III) serving as a raw material through a dicarbonylation reaction for 4-8 hours in an organic solvent at the temperature of 60-100 ℃. The method has the advantages of simple process, high yield and low cost, and the substitution position of the carbazole ring is NH-; the yield of the prepared product can reach 92 percent. |
