Intramolecular trapping of intermediates of the copper-ketocarbene type by the double bond of monocyclic olefins leads to a variety of tricyclic ketones. The photolytically generated ketocarbene cannot be trapped in this way to a significant degree. Sufficient examples of the method are given to indicate its general usefulness in the synthesis of ketocyclopropanes.
