Factory wholesale Hydroxypropyl Methyl Cellulose - 2-Methylbenzophenone With CAS 131-58-8 – Unilong

2-Methylbenzophenone is a benzophenone compound, which is 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 ketones are very important synthetic building blocks in organic synthesis, which widely exist in the core structures of natural products and are widely used in biologically active compounds.

Under the protection of inert gas, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) and biquinoline (bq, 3 mol %) were dispersed in an organic solvent (2 mL) ), then H2O (2 mmol) was added, and the temperature was raised to 80°C for 6 hours. Then the reaction solution was extracted three times with Et2O (5 mL), the organic phases were combined, and the solvent was spin-dried under reduced pressure. The obtained crude product was subjected to column chromatography on a silica gel column (300-400 mesh), and the eluents were petroleum ether and ethyl acetate. , to obtain the target product 2-methylbenzophenone. Chemical properties Colorless or light yellow transparent liquid. The melting point is about 134°C. Use as a pharmaceutical intermediate.
