Copper(II)-catalyzed aromatization followed by bromination of cyclohexenones leading to phenols and bromophenols
Conversion of substituted cyclohexenones into the corresponding phenols can be achieved using copper acetate as the catalyst in the presence of LiBr and CF3COOH under oxygen. With the use of excess LiBr, electrophilic aromatic bromination afforded the corresponding bromophenol under similar catalytic conditions. Copyright

The Chemistry of Terpenes. Part 27.1 The Halogenation of (+)-Thujone and of (-)-Carvotanacetone, and the Stereochemistry and Mechanism of Formation of 'Tribromothujone'
The groos structure and precise stereochemistry of 'tribromothujone' have been identified; its adjacent bromine atoms are cis-orientated.The mechanism of its formation is discussed.A number of halogenated compounds derived from (+)-thujone have been obtained and their absolute configurations determined. (-)-Carvotanacetone dibromide and two tribromides have stereochemically identified.
