  4. 2-Methylpyridine - Wikipedia

    en.wikipedia.org/wiki/2-Methylpyridine

    2-Methylpyridine, or 2-picoline, is the compound described with formula C 6 H 7 N. 2-Picoline is a colorless liquid that has an unpleasant odor similar to pyridine. It is mainly used to make vinylpyridine and the agrichemical nitrapyrin .

  5. 4-Methylpyridine - Wikipedia

    en.wikipedia.org/wiki/4-Methylpyridine

    4-Methylpyridine is the organic compound with the formula CH 3 C 5 H 4 N. It is one of the three isomers of methylpyridine. This pungent liquid is a building block for the synthesis of other heterocyclic compounds. Its conjugate acid, the 4-methylpyridinium ion, has a pK a of 5.98, about 0.7 units above that of pyridine itself. [1]

    H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides.

  7. 3-Methylpyridine - Wikipedia

    en.wikipedia.org/wiki/3-Methylpyridine

    Chlorpyrifos is produced from 3,5,6-trichloro-2-pyridinol, which is generated from 3-picoline by way of cyanopyridine. This conversion involves the ammoxidation of 3-methylpyridine: CH 3 C 5 H 4 N + 1.5 O 2 + NH 3 → NCC 5 H 4 N + 3 H 2 O. 3-Cyanopyridine is also a precursor to 3-pyridinecarboxamide, [3] [4] [5] which is a precursor to ...

    The Chichibabin pyridine synthesis (/ ˈ tʃ iː tʃ iː ˌ b eɪ b iː n /) is a method for synthesizing pyridine rings. The reaction involves the condensation reaction of aldehydes , ketones , α,β-Unsaturated carbonyl compounds , or any combination of the above, with ammonia . [ 1 ]

  9. 2-Chloropyridine - Wikipedia

    en.wikipedia.org/wiki/2-Chloropyridine

    In these conversions, chloride is displaced. [2] Pyrithione, the conjugate base of 2-mercaptopyridine-N-oxide, is a fungicide found in some shampoos. Oxidation 2-chloropyridine gives 2-chloropyridine-N-oxide. [5] The antihistamine pheniramine may be generated via the reaction of phenylacetonitrile with 2-chloropyridine in the presence of a base ...
