  2. Ethyl bromodifluoroacetate - Wikipedia

    en.wikipedia.org/wiki/Ethyl_bromodifluoroacetate

    Ethyl bromodifluoroacetate is an ester with the chemical formula F 2 Br C H−CO 2 CH 2 CH 3. It can be used to introduce the CF 2 group when synthesising chemical compounds. It is a colorless to yellow liquid. It is an ethyl ester of bromodifluoroacetic acid.

  3. 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 ...

  4. Fluoroalcohol - Wikipedia

    en.wikipedia.org/wiki/Fluoroalcohol

    Most primary and secondary perfluoroalcohols are unstable, for example trifluoromethanol eliminates hydrogen fluoride, forming carbonyl fluoride. [2] This reaction is reversible. [3] CF 3 OH → COF 2 + HF. Stable perfluorinated alcohols include nonafluoro-tert-butyl alcohol ((CF 3) 3 COH) and pentafluorophenol (C 6 F 5 OH).

    C 6 H 6 + HOSO 2 Cl → C 6 H 5 SO 3 H + HCl C 6 H 5 SO 3 H + HOSO 2 Cl → C 6 H 5 SO 2 Cl + H 2 SO 4. The intermediate benzenesulfonic acid can be chlorinated with thionyl chloride as well. Benzenesulfonyl chloride, the most important sulfonyl halide, can also be produced by treating sodium benzenesulfonate with phosphorus pentachlorides. [5]

    en.wikipedia.org/wiki/Pinnick_Oxidation

    The typical reaction conditions used today were developed by G. A. Kraus. [2] [3] H.W. Pinnick later demonstrated that these conditions could be applied to oxidize α,β-unsaturated aldehydes. [4] There exist many different reactions to oxidize aldehydes, but only a few are amenable to a broad range of functional groups.

  7. Dibromomethane - Wikipedia

    en.wikipedia.org/wiki/Dibromomethane

    The bromochloromethane product from either reaction can further react in a similar manner: 6 CH 2 BrCl + 3 Br 2 + 2 Al → 6 CH 2 Br 2 + 2 AlCl 3 CH 2 BrCl + HBr → CH 2 Br 2 + HCl. In the laboratory, it is prepared from bromoform using sodium arsenite and sodium hydroxide: [4] CHBr 3 + Na 3 AsO 3 + NaOH → CH 2 Br 2 + Na 3 AsO 4 + NaBr

  9. Hell–Volhard–Zelinsky halogenation - Wikipedia

    en.wikipedia.org/wiki/Hell–Volhard–Zelinsky...

    An example of the Hell–Volhard–Zelinsky reaction can be seen in the preparation of alanine from propionic acid.In the first step, a combination of bromine and phosphorus tribromide is used in the Hell–Volhard–Zelinsky reaction to prepare 2-bromopropionic acid, [3] which in the second step is converted to a racemic mixture of the amino acid product by ammonolysis.
