  2. Propionaldehyde - Wikipedia

    en.wikipedia.org/wiki/Propionaldehyde

    Propionaldehyde may also be prepared by oxidizing 1-propanol with a mixture of sulfuric acid and potassium dichromate. The reflux condenser contains water heated at 60 °C, which condenses unreacted propanol, but allows propionaldehyde to pass. The propionaldehyde vapor is immediately condensed into a suitable receiver.

  3. 1-Bromopropane - Wikipedia

    en.wikipedia.org/wiki/1-Bromopropane

    The latter reaction is also viable laboratory synthesis. One laboratory technique for substitutive bromination treats propanol with a mixture of hydrobromic and sulfuric acids: CH 3 CH 2 CH 2 OH + HBr → CH 3 CH 2 CH 2 Br + H 2 O. Alternate synthetic routes include treating propanol with phosphorus tribromide [4] or via a Hunsdiecker reaction ...

  4. Propiolaldehyde - Wikipedia

    en.wikipedia.org/wiki/Propiolaldehyde

    Boiling point 54–57 °C (129–135 °F; 327–330 K) Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

  5. 2-Bromopropane - Wikipedia

    en.wikipedia.org/wiki/2-Bromopropane

    Boiling point: 59 to 61 °C; 138 to 142 °F; 332 to 334 K ... It is used for introducing the isopropyl functional group in organic synthesis. 2-Bromopropane is ...

  6. Tropinone - Wikipedia

    en.wikipedia.org/wiki/Tropinone

    The synthesis is a good example of a biomimetic reaction or biogenetic-type synthesis because biosynthesis makes use of the same building blocks. It also demonstrates a tandem reaction in a one-pot synthesis. Furthermore, the yield of the synthesis was 17% and with subsequent improvements exceeded 90%. [5]

  7. Propionitrile - Wikipedia

    en.wikipedia.org/wiki/Propionitrile

    Propionitrile is a solvent similar to acetonitrile but with a slightly higher boiling point. It is a precursor to propylamines by hydrogenation. It is a precursor to propylamines by hydrogenation. It is a C-3 building block in the preparation of the drug flopropione by the Houben-Hoesch reaction .

  8. 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.

  9. One-pot synthesis - Wikipedia

    en.wikipedia.org/wiki/One-pot_synthesis

    An example of a one-pot synthesis is the total synthesis of tropinone or the Gassman indole synthesis. Sequential one-pot syntheses can be used to generate even complex targets with multiple stereocentres, such as oseltamivir, [1] which may significantly shorten the number of steps required overall and have important commercial implications.
