The reaction of the lithium-containing derivative of dicyclopropyl ketone with chloro(triphenylphosphine)gold has been shown to produce two organogold derivatives of the cyclopropane series.The lithium-containing derivative of dicyclopropyl ketone was obtained by treating dicyclopropyl ketone with lithium diisopropylamide.Depending on the molar ratio of the starting ketone and lithium diisopropylamide, the reaction of auration proceeds by two different modes: with the formation of aurated dicyclopropyl ketone or aurated tetracyclopropyl hydroxyketone.Dicyclopropyl ketone undergoes aldol condensation in the presence of lithium diisopropylamide.All the compounds synthesized were characterised by IR. 1H and 13C NMR spectroscopic data.The strucutre of aurated dicyclopropyl ketone was determined by X-ray crystal analysis.
