  2. Cornforth reagent - Wikipedia

    en.wikipedia.org/wiki/Cornforth_reagent

    [2] [3] The Cornforth reagent is a strong oxidizing agent which can convert primary and secondary alcohols to aldehydes and ketones respectively. In its chemical structure and functions it is closely related to other compounds made from hexavalent chromium oxide, such as pyridinium chlorochromate and Collins reagent. Because of their toxicity ...

  3. Semicarbazone - Wikipedia

    en.wikipedia.org/wiki/Semicarbazone

    Many semicarbazones are crystalline solids, useful for the identification of the parent aldehydes/ketones by melting point analysis. [ 1 ] A thiosemicarbazone is an analog of a semicarbazone which contains a sulfur atom in place of the oxygen atom.

  4. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    A ketone compound containing a carbonyl group (C=O) For organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom.

  5. Semicarbazide - Wikipedia

    en.wikipedia.org/wiki/Semicarbazide

    Semicarbazide is frequently reacted with aldehydes and ketones to produce semicarbazones via a condensation reaction.This is an example of imine formation resulting from the reaction of a primary amine with a carbonyl group.

  6. Büchner–Curtius–Schlotterbeck reaction - Wikipedia

    en.wikipedia.org/wiki/Büchner–Curtius...

    The Buchner–Curtius–Schlotterbeck reaction is the reaction of aldehydes or ketones with aliphatic diazoalkanes to form homologated ketones. [1] It was first described by Eduard Buchner and Theodor Curtius in 1885 [2] and later by Fritz Schlotterbeck in 1907. [3]

  7. Darzens reaction - Wikipedia

    en.wikipedia.org/wiki/Darzens_reaction

    The Darzens reaction (also known as the Darzens condensation or glycidic ester condensation) is the chemical reaction of a ketone or aldehyde with an α-haloester in the presence of a base to form an α,β-epoxy ester, also called a "glycidic ester".

  8. Tollens' reagent - Wikipedia

    en.wikipedia.org/wiki/Tollens'_reagent

    Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.

  9. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
