  2. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  3. Alcohol oxidation - Wikipedia

    en.wikipedia.org/wiki/Alcohol_oxidation

    The oxidation of primary alcohols to carboxylic acids normally proceeds via the corresponding aldehyde, which is transformed via an aldehyde hydrate (gem-diol, R-CH(OH) 2) by reaction with water. Thus, the oxidation of a primary alcohol at the aldehyde level without further oxidation to the carboxylic acid is possible by performing the reaction ...

  4. Benzene - Wikipedia

    en.wikipedia.org/wiki/Benzene

    Benzene is an organic chemical compound with the molecular formula C 6 H 6. The benzene molecule is composed of six carbon atoms joined in a planar hexagonal ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.

  5. Carbonyl oxidation with hypervalent iodine reagents - Wikipedia

    A key iodine(III) enolate intermediate forms, which then undergoes either nucleophilic substitution (α-functionalization), elimination (dehydrogenation), or rearrangement. Common hypervalent iodine reagents used to effect these transformations include iodosylbenzene (PhIO), [1] Koser's reagent (PhI(OTs)OH), [1] and (dichloroiodo)benzene (PhICl ...

  6. Cannizzaro reaction - Wikipedia

    en.wikipedia.org/wiki/Cannizzaro_reaction

    2 C 6 H 5 CHO + KOH → C 6 H 5 CH 2 OH + C 6 H 5 COOK. The process is a redox reaction involving transfer of a hydride from one substrate molecule to the other: one aldehyde is oxidized to form the acid, the other is reduced to form the alcohol. [3]

  7. Dehydrohalogenation - Wikipedia

    en.wikipedia.org/wiki/Dehydrohalogenation

    In general, the reaction of a haloalkane with potassium hydroxide can compete with an S N 2 nucleophilic substitution reaction by OH − a strong, unhindered nucleophile. Alcohols are however generally minor products. Dehydrohalogenations often employ strong bases such as potassium tert-butoxide (K + [CH 3] 3 CO −).

  9. Wolff–Kishner reduction - Wikipedia

    en.wikipedia.org/wiki/Wolff–Kishner_reduction

    The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. [1] [2] In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.
