2-Chloromethylpyridine is an organohalide that consists of a pyridine core bearing a chloromethyl group. It is one of three isomeric chloromethylpyridines, along with 3- and 4-chloromethylpyridine. It is an alkylating agent . 2-Chloromethylpyridine is a precursor to pyridine-containing ligands .
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 .
All isomers share the molecular weight 123,11 g/mol and the chemical formula C 6 H 5 NO 2 ... Text is available under the Creative Commons Attribution-ShareAlike 4.0 ...
[4] [5] By 1870, the German chemist Adolf von Baeyer had synthesized picoline in two ways: by the dry distillation of acroleïnammoniak (CH 2 =CH-CH=N-CHOH-CH=CH 2) [6] and by heating tribromallyl (1,2,3-tribromopropane) with ammonia in ethanol. [7] In 1871, the English chemist and physicist James Dewar speculated that picoline was ...
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]
Chemical structure of chloromethyl methyl ether (MOM-Cl) Chloroalkyl ethers are a class of organic compounds with the general structure R-O-(CH 2) n-Cl, characterized as an ether connected to a chloromethyl group via an alkane chain. Chloromethyl methyl ether (CMME) is an ether with the formula C H 3 OCH 2 Cl.
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 ...
Of the many variations have been explored. one approach employs nitriles as the nitrogen source. For example, acrylonitrile and acetone affords 2-methylpyridine uncontaminated with the 4-methyl derivative. In another variation, alkynes and nitriles react in the presence of organocobalt catalysts, a reaction inspired by alkyne trimerization. [5]
