Cyclic examples of these compounds are formed using nitrous acid in a ring- expanding reaction known as the Tiffeneau-Demjanov rearrangement.
Cyclic examples of these compounds are formed using nitrous acid in a ring- expanding reaction known as the Tiffeneau-Demjanov rearrangement. A phenol bound to one of these functional groups can be formed from an O-phenyl-ester via either photochemical excitation or with a Lewis acid like aluminum trichloride. The Hajos-Parrish reaction can be used to synthesize a bicyclic one of these compounds which is commonly used as a precursor inthe organic synthesis of many steroids. An alpha, beta unsaturated one of these compounds found in a 6-membered ring is formed in a reaction which consists of a Michael addition followed byan aldol condensation and is called the Robinson annulation. Oxidizing a secondary alcohol will yield one of these compounds. For 10 points, name these compounds in which two R groups flank a carbonyl, which are contrasted with aldehydes.

ketones [prompt on "carbonyl," accept "Wieland-Miescher ketone" Note: the reaction in the second clue is the Fries rearrangement]
