The reaction of cycloheptatriene with acyl halides in the presence of Lewis acids. A convenient synthesis of 1-acylcycloheptatrienes
Abstract
The reaction of cycloheptatriene with acyl halides in the presence of a Lewis acid does not involve a hydride-atom transfer. The reaction has been used to prepare two series of compounds, (a) benzyl ketones, and (b) 1-acylcycloheptatrienes. An intermediate common to both reactions has been identified, allowing a coherent mechanism to be postulated.
