Another reaction that makes six-membered rings usually begins with a Michael addition of two of these compounds to an enolate and proceeds with an aldol condensation to an enone.
Assimomytis et al. used LDA to catalyze an unusually anionic version of one reaction that creates these compounds, and that reaction that makes these compounds has a photo- variant that proceeds via a mechanism involving the cleavage of a carbon-oxygen bond to produce a radical with three distinct resonance structures. Another reaction that makes six-membered rings usually begins with a Michael addition of two of these compounds to an enolate and proceeds with an aldol condensation to an enone. Those reactions are the Fries rearrangement and Robinson annulation. A negative result in the Tollens test for these compounds distinguishes them from aldehydes. For 10 points, name this type of compound with a carbonyl group bonded to two different substituents, the simplest of which is acetone.
