  2. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...

  3. Transhalogenation - Wikipedia

    en.wikipedia.org/wiki/Transhalogenation

    A common method is halide metathesis. An example is the conversion of alkyl chloride into alkyl fluoride: . C 3 H 5-Cl + NaF → R-F + NaCl. This kind of reaction is called Finkelstein reaction. [2]

  4. Swarts fluorination - Wikipedia

    en.wikipedia.org/wiki/Swarts_fluorination

    Swarts fluorination is a process whereby the chlorine atoms in a compound – generally an organic compound, but experiments have been performed using silanes – are replaced with fluorine, by treatment with antimony trifluoride in the presence of chlorine or of antimony pentachloride.

  5. Williamson ether synthesis - Wikipedia

    en.wikipedia.org/wiki/Williamson_ether_synthesis

    This reaction was developed by Alexander Williamson in 1850. [2] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction. This reaction is important in the history of organic chemistry because it helped prove the structure of ethers. The general reaction mechanism is as follows: [3]

  6. Sandmeyer reaction - Wikipedia

    en.wikipedia.org/wiki/Sandmeyer_reaction

    The Sandmeyer reaction is an example of a radical-nucleophilic aromatic substitution (S RN Ar). The radical mechanism of the Sandmeyer reaction is supported by the detection of biaryl byproducts. [8]

    Hans Finkelstein (17 May 1885, Leipzig, Germany - December 1938) was a German chemist. He is particularly known for the Finkelstein reaction developed by and named after him. [ 1 ] [ 2 ]

  9. David Finkelstein - Wikipedia

    en.wikipedia.org/wiki/David_Finkelstein

    David Finkelstein was the first, in 1958, who identified Schwarzschild's solution of the Einstein field equations as corresponding to a region in space from which nothing escapes. [ 4 ] [ 5 ] In 1959, Finkelstein and Charles W. Misner found the gravitational kink, a topological defect in the gravitational metric, whose quantum theory could ...
