| Application | benzophenone imine is a commonly used reagent that can be used as a protecting group for primary amines. In particular, it is widely used in amino acid chemistry and can also be reacted with aryl halides to prepare aromatic amines. |
| Use | for organic synthesis. |
| production method | benzophenone oxime is heated and decomposed to generate benzophenone and benzophenone imine, and dry hydrogen chloride gas is introduced into the reaction mixture, the benzophenone imine is precipitated into a salt, the imine salt is filtered out, and then neutralized with a base to obtain free benzophenone imine. |
