Carbocationic cyclisations and hydroxylations initiated by dehalogenation of terminally unsaturated α-bromo-ketones
Abstract
Action of Ag+SbF6– on the linear terminally unsaturated α-bromoketones (3)–(5) leads, via the oxonium salts (12)–(14), to the regio- and stereo-specifically substituted cyclohexanols (6)–(8).
