Preparation of 2-acyl-6-methylnaphthalenes |
| abstract |
A regioselective acetylation process is provided for converting a 2-methylnaphthalene compound to a 2-acetyl-6-methylnaphthalene compound. The process is conducted under liquid phase conditions using a new complexing agent which is regiospecific for the beta position of naphthalene and which is an electron-rich, carbon-based compound. A preferred such agent is hexamethylbenzene. Also provided is a novel method for producing a 2-acetyl-6-methylnaphthalene compound of relative high purity from isomer mixtures by recrystallization from a hydrocarbon solvent, such as n-octane, isooctane, or n-nonane. |
