Novel aromatic systems. Part XI. Preparation of 1,2-dihydroxybenzocycloheptenes
Abstract
1-Hydroxy- and 1-methoxy-benzocyclohepten-2-one, 2-methoxybenzocyclohepten-1-one, and 5-phenylbenzo-cyclohepten-2-one have been synthesised: they are only stable in solution. Unsuccessful attempts to prepare 6-methoxyinden-5-ones are recorded.
