  2. Blanc chloromethylation - Wikipedia

    en.wikipedia.org/wiki/Blanc_chloromethylation

    The benzyl alcohol thus formed is quickly converted to the chloride under the reaction conditions. Mechanism of Blanc chloromethylation. Other possibilities for the electrophile include (chloromethyl)oxonium cation (ClH 2 C–OH 2 +) or chlorocarbenium cation (ClCH 2 +), which may be formed in the presence of zinc chloride. [4]

  3. Benzyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzyl_chloride

    Benzoic acid (C 6 H 5 COOH) can be prepared by oxidation of benzyl chloride in the presence of alkaline KMnO 4: C 6 H 5 CH 2 Cl + 2 KOH + 2 [O] → C 6 H 5 COOK + KCl + H 2 O. Benzyl chloride may be used in the synthesis of amphetamine-class drugs, and for this reason, sales of benzyl chloride are monitored as a List II drug precursor chemical ...

  4. Benzylamine - Wikipedia

    en.wikipedia.org/wiki/Benzylamine

    Benzylamine, also known as phenylmethylamine, is an organic chemical compound with the condensed structural formula C 6 H 5 CH 2 NH 2 (sometimes abbreviated as PhCH 2 NH 2 or BnNH 2).It consists of a benzyl group, C 6 H 5 CH 2, attached to an amine functional group, NH 2.

  5. Curtius rearrangement - Wikipedia

    en.wikipedia.org/wiki/Curtius_rearrangement

    The Curtius rearrangement (or Curtius reaction or Curtius degradation), first defined by Theodor Curtius in 1885, is the thermal decomposition of an acyl azide to an isocyanate with loss of nitrogen gas. [1] [2] The isocyanate then undergoes attack by a variety of nucleophiles such as water, alcohols and amines, to yield a primary amine ...

  6. Menshutkin reaction - Wikipedia

    en.wikipedia.org/wiki/Menshutkin_reaction

    Menshutkin-reaction. The reaction is the method of choice for the preparation of quaternary ammonium salts. [1] Some phase transfer catalysts (PTC) can be prepared according to the Menshutkin reaction, for instance the synthesis of triethyl benzyl ammonium chloride (TEBA) from triethylamine and benzyl chloride: Menshutkin reaction

  7. Schotten–Baumann reaction - Wikipedia

    en.wikipedia.org/wiki/Schotten–Baumann_reaction

    [1] [2] The name "Schotten–Baumann reaction conditions" often indicate the use of a two-phase solvent system, consisting of water and an organic solvent. The base within the water phase neutralizes the acid, generated in the reaction, while the starting materials and product remain in the organic phase, often dichloromethane or diethyl ether.

  9. Leuckart reaction - Wikipedia

    en.wikipedia.org/wiki/Leuckart_reaction

    The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines. The reaction is an example of reductive amination. [1] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. It requires high temperatures, usually between 120 and 130 °C; for the ...
