    The acid chloride then reacts with diazomethane (R 2 = H), or occasionally a diazoalkyl, via the Arndt-Eistert procedure, to generate an α-diazo ketone, which will undergo a metal-catalyzed or photolyzed Wolff rearrangement, to give a ketene. The ketene can be trapped with any weak acid, such as an alcohol or amine, to form the ester or amide.

    The bicycle is then opened by nucleophilic attack on the ketone to give the contracted product. [19] This reaction has been used to convert cyclohexanone to the methyl ester of cyclopropanecarboxylic acid. A generalized mechanism of the Favorskii rearrangement to give a ring contracted product. Note that anion formation has been omitted.

    en.wikipedia.org/wiki/Baeyer–Villiger_oxidation

    The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant. [1] The reaction is named after Adolf von Baeyer and Victor Villiger who first reported the reaction in 1899. [1] Baeyer-Villiger oxidation

    The Reformatsky reaction (sometimes transliterated as Reformatskii reaction) is an organic reaction which condenses aldehydes or ketones with α-halo esters using metallic zinc to form β-hydroxy-esters: [1] [2] The Reformatsky reaction. The organozinc reagent, also called a 'Reformatsky enolate', is prepared by treating an alpha-halo ester ...

  9. Fehling's solution - Wikipedia

    en.wikipedia.org/wiki/Fehling's_solution

    Fehling's solution can be used to distinguish aldehyde vs ketone functional groups. The compound to be tested is added to the Fehling's solution and the mixture is heated. Aldehydes are oxidized, giving a positive result, but ketones do not react, unless they are α-hydroxy ketones.
