  2. Organic reaction - Wikipedia

    en.wikipedia.org/wiki/Organic_reaction

    The oldest organic reactions are combustion of organic fuels and saponification of fats to make soap. Modern organic chemistry starts with the Wöhler synthesis in 1828. In the history of the Nobel Prize in Chemistry awards have been given for the invention of specific organic reactions such as the Grignard reaction in 1912, the Diels–Alder ...

  4. Sommelet reaction - Wikipedia

    en.wikipedia.org/wiki/Sommelet_reaction

    The Sommelet reaction is an organic reaction in which a benzyl halide is converted to an aldehyde by action of hexamine and water. [1] [2] It is named after the French chemist Marcel Sommelet, who first reported the reaction in 1913. [3] One example, thiophene-2-carboxaldehyde is prepared by the reaction of hexamine with 2-chloromethylthiophene ...

  5. Corey–House synthesis - Wikipedia

    en.wikipedia.org/wiki/Corey–House_synthesis

    The Corey–House synthesis (also called the Corey–Posner–Whitesides–House reaction and other permutations) is an organic reaction that involves the reaction of a lithium diorganylcuprate with an organic halide or pseudohalide (′) to form a new alkane, as well as an ill-defined organocopper species and lithium (pseudo)halide as byproducts.

  6. Henry reaction - Wikipedia

    en.wikipedia.org/wiki/Henry_reaction

    The Henry reaction is a classic carbon–carbon bond formation reaction in organic chemistry. Discovered in 1895 by the Belgian chemist Louis Henry (1834–1913), it is the combination of a nitroalkane and an aldehyde or ketone in the presence of a base to form β-nitro alcohols.

  7. Stevens rearrangement - Wikipedia

    en.wikipedia.org/wiki/Stevens_rearrangement

    The reaction mechanism of the Stevens rearrangement is one of the most controversial reaction mechanisms in organic chemistry. [4] Key in the reaction mechanism [5] [6] for the Stevens rearrangement (explained for the nitrogen reaction) is the formation of an ylide after deprotonation of the ammonium salt by a strong base.

  8. List of unsolved problems in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Why are accelerated kinetics observed for some organic reactions at the water-organic interface? [5] [non-primary source needed] Do replacement reactions of aryl diazonium salts (dediazotizations) predominantly undergo S N 1 or a radical mechanism? [6] Can an electrochemical cell reliably perform organic redox reactions? [7]

  9. Pericyclic reaction - Wikipedia

    en.wikipedia.org/wiki/Pericyclic_reaction

    Example of a pericycle reaction: the norcaradiene–cyclohexatriene rearrangement. In organic chemistry, a pericyclic reaction is the type of organic reaction wherein the transition state of the molecule has a cyclic geometry, the reaction progresses in a concerted fashion, and the bond orbitals involved in the reaction overlap in a continuous cycle at the transition state.
