  2. Propionaldehyde - Wikipedia

    en.wikipedia.org/wiki/Propionaldehyde

    Propionaldehyde exhibits the reactions characteristic of alkyl aldehydes, e.g. hydrogenation, aldol condensations, oxidations, etc. It is the simplest aldehyde with a prochiral methylene such that α-functionalized derivatives (CH 3 CH(X)CHO) are chiral. If water is available, propionaldehyde exists in equilibrium with 1,1-propanediol, a ...

  3. Propiolaldehyde - Wikipedia

    en.wikipedia.org/wiki/Propiolaldehyde

    Another possible pathway is through the reaction of propynylidyne (C 3 H) with water. [4] Hazards. The compound is explosive, possibly because it tends to polymerize. [1]

  4. Pinacol coupling reaction - Wikipedia

    en.wikipedia.org/wiki/Pinacol_coupling_reaction

    The pinacol reaction is extremely well-studied and tolerates many different reductants, including electrochemical syntheses.Variants are known for homo- and cross-coupling, intra- and inter-molecular reactions with appropriate diastereo- or enantioselectivity; [2] as of 2006, the only unsettled frontier was enantioselective cross-coupling of aliphatic aldehydes. [3]

  5. Knoevenagel condensation - Wikipedia

    en.wikipedia.org/wiki/Knoevenagel_condensation

    A Knoevenagel condensation is a nucleophilic addition of an active hydrogen compound to a carbonyl group followed by a dehydration reaction in which a molecule of water is eliminated (hence condensation). The product is often an α,β-unsaturated ketone (a conjugated enone). General Knoevenagel layout

  6. Proline-catalyzed aldol reactions - Wikipedia

    en.wikipedia.org/wiki/Proline-catalyzed_aldol...

    The Hajos–Parrish–Eder–Sauer–Wiechert and Barbas-List [1] reactions in organic chemistry are a family of proline-catalysed asymmetric aldol reactions.. In the 1970s, two research groups discovered (and published) almost simultaneously their discoveries of two related intramolecular reactions: Zoltan Hajos and David Parrish at Hoffmann-La Roche [2] [3] and Rudolf Wiechert et al at ...

  7. 2-Phenyl-2-propanol - Wikipedia

    en.wikipedia.org/wiki/2-Phenyl-2-propanol

    2-Phenyl-2-propanol can either be applied in organic syntheses, or be reactants or intermediates in agrochemical, medical, and dyestuff fields. [ 2 ] 2-Phenyl-2-propanol is the main metabolite of cumene , and therefore 2-phenyl-2-propanol can serve as a biomarker of cumene.

  8. 1-Propanol - Wikipedia

    en.wikipedia.org/wiki/1-Propanol

    1-Propanol (also propan-1-ol, propanol, n-propyl alcohol) is a primary alcohol with the formula CH 3 CH 2 CH 2 OH and sometimes represented as PrOH or n-PrOH.It is a colourless liquid and an isomer of 2-propanol. 1-Propanol is used as a solvent in the pharmaceutical industry, mainly for resins and cellulose esters, and, sometimes, as a disinfecting agent.

  9. Cannizzaro reaction - Wikipedia

    en.wikipedia.org/wiki/Cannizzaro_reaction

    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
