  3. Carbon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–oxygen_bond

    A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1] [2] [3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides, carbonates and metal carbonyls, [4] and in organic compounds such as alcohols, ethers, and carbonyl compounds.

  4. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    In 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. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acid ), as part of many larger functional groups.

  5. Dakin oxidation - Wikipedia

    en.wikipedia.org/wiki/Dakin_oxidation

    The Dakin oxidation can occur in mild acidic conditions as well, with a mechanism analogous to the base-catalyzed mechanism. In methanol, hydrogen peroxide, and catalytic sulfuric acid, the carbonyl oxygen is protonated (14), after which hydrogen peroxide adds as a nucleophile to the carbonyl carbon, forming a tetrahedral intermediate (15).

  6. Carbonyl α-substitution reaction - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_α-substitution...

    A hydrogen on the α position of a carbonyl compound is weakly acidic and can be removed by a strong base to yield an enolate ion. In comparing acetone (pK a = 19.3) with ethane (pK a = 60), for instance, the presence of a neighboring carbonyl group increases the acidity of the ketone over the alkane by a factor of 10 40.

  7. Metal cluster compound - Wikipedia

    en.wikipedia.org/wiki/Metal_cluster_compound

    The compound is prepared from oxidation of K 4 Pb 9 [15] by Au + in PPh 3 AuCl (by reaction of tetrachloroauric acid and triphenylphosphine) in ethylene diamine with 2.2.2-crypt. This type of cluster was already known as is the endohedral Ni@Pb 10 2− (the cage contains one nickel atom).

  8. Insertion reaction - Wikipedia

    en.wikipedia.org/wiki/Insertion_reaction

    Organic azides also provide an example of an insertion reaction in organic synthesis and, like the above examples, the transformations proceed with loss of nitrogen gas. When tosyl azide reacts with norbornadiene, a ring expansion reaction takes place in which a nitrogen atom is inserted into a carbon-carbon bond α- to the bridge head: [14]

  9. Oxocarbenium - Wikipedia

    en.wikipedia.org/wiki/Oxocarbenium

    In organic reactions, ketones are commonly activated by the coordination of a Lewis acid or Brønsted acid to the oxygen to generate an oxocarbenium ion as an intermediate. Numerically, a typical partial charge (derived from Hartree-Fock computations) for the carbonyl carbon of a ketone R 2 C=O (like acetone) is δ+ = 0.51.
