  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 ...

    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. Mannich reaction - Wikipedia

    en.wikipedia.org/wiki/Mannich_reaction

    In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl (C=O) functional group by formaldehyde (H−CHO) and a primary or secondary amine (−NH 2) or ammonia (NH 3). [1]

  6. Silyl enol ether - Wikipedia

    en.wikipedia.org/wiki/Silyl_enol_ether

    The general structure of a silyl enol ether. In organosilicon chemistry, silyl enol ethers are a class of organic compounds that share the common functional group R 3 Si−O−CR=CR 2, composed of an enolate (R 3 C−O−R) bonded to a silane (SiR 4) through its oxygen end and an ethene group (R 2 C=CR 2) as its carbon end.

  7. Cyclopropanation - Wikipedia

    en.wikipedia.org/wiki/Cyclopropanation

    In organic chemistry, cyclopropanation refers to any chemical process which generates cyclopropane ((CH 2) 3) rings.It is an important process in modern chemistry as many useful compounds bear this motif; for example pyrethroid insecticides and a number of quinolone antibiotics (ciprofloxacin, sparfloxacin, etc.).

  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. Schöllkopf method - Wikipedia

    en.wikipedia.org/wiki/Schöllkopf_method

    The Schöllkopf method or Schöllkopf Bis-Lactim Amino Acid Synthesis is a method in organic chemistry for the asymmetric synthesis of chiral amino acids. [1] [2] The method was established in 1981 by Ulrich Schöllkopf. [3] [4] [5] In it glycine is a substrate, valine a chiral auxiliary and the reaction taking place an alkylation.
