application | 2-methylbenzophenone is a benzophenone compound and a very important fine chemical. At the same time, ketones are also the core structures of many organic molecules, such as functional materials, fragrances and drug molecules. Aromatic ketone is a very important synthetic block in organic synthesis, which widely exists in the core structure of natural products and is widely used in bioactive compounds. |
preparation | under the protection of inert gas, 2-methylphenylsulfonylhydrazide (1.1mmol), benzonitrile (1.0mmol), palladium catalyst (2mol%) and biquinoline (bq,3mol%) are dispersed in an organic solvent (2mL), then H2O(2mmol) is added, and the temperature is raised to 80 ℃ for reaction for 6 hours. Then the reaction liquid was extracted three times with Et2O(5mL), the organic phase was combined, and the solvent was decompressed and dried. The crude product was subjected to column chromatography with silica gel column (300-400 mesh), and the eluent was a mixture of petroleum ether and ethyl acetate to obtain the target product 2-methyl benzophenone. |
