    Thus, the yield of the valuable chemical is high, although the atom economy can be low. The final stage in the synthesis of pentaerythritol is an example. A solvent-free reaction has been reported involving grinding liquid 2-chlorobenzaldehyde with potassium hydroxide in a mortar and pestle: [7] Solvent-free Cannizzaro reaction

  3. 4-Chlorobenzaldehyde - Wikipedia

    en.wikipedia.org/wiki/4-Chlorobenzaldehyde

    4-Chlorobenzaldehyde (o-Chlorobenzaldehyde) is an organic compound with the formula ClC 5 H 4 CHO. It is one of three isomeric monochlorinated benzaldehydes. Preparation

  4. Chlorobenzaldehyde - Wikipedia

    Chlorobenzaldehyde may refer to: 2-Chlorobenzaldehyde (o-chlorobenzaldehyde) 3-Chlorobenzaldehyde (m-chlorobenzaldehyde) 4-Chlorobenzaldehyde (p-chlorobenzaldehyde)

  5. Benzaldehyde - Wikipedia

    en.wikipedia.org/wiki/Benzaldehyde

    Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...

  6. Solvent effects - Wikipedia

    en.wikipedia.org/wiki/Solvent_effects

    In chemistry, solvent effects are the influence of a solvent on chemical reactivity or molecular associations. Solvents can have an effect on solubility, stability and reaction rates and choosing the appropriate solvent allows for thermodynamic and kinetic control over a chemical reaction.

  7. 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.

  8. Aldol condensation - Wikipedia

    en.wikipedia.org/wiki/Aldol_condensation

    An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone.

  9. Debus–Radziszewski imidazole synthesis - Wikipedia

    en.wikipedia.org/wiki/Debus–Radziszewski...

    A modification of this general method, where one equivalent of ammonia is replaced by an amine, affords N-substituted imidazoles in good yields. [ 3 ] This reaction has been applied to the synthesis of a range of 1,3-dialkylimidazolium ionic liquids by using various readily available alkylamines.
