2,6-Dichloropyridine is a chloropyridine with the formula C 5 H 3 Cl 2 N. A white solid, it is one of six isomers of dichloropyridine . It serves as a precursor to the antibiotic enoxacin , [ 2 ] as well as the drug and anpirtoline and the antifungal liranaftate .
Dichloropyridines are organic compounds with the formula Cl 2 C 5 H 3 N, consisting of a pyridine ring substituted with two chlorides. [1] Six isomers are known. They ...
Around 75,000 people in the study used some type of medication to treat alcohol use disorder. Among that group, the team documented about 30,000 hospitalizations.
2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (or DDQ) is the chemical reagent with formula C 6 Cl 2 (CN) 2 O 2. This oxidant is useful for the dehydrogenation of alcohols, [3] phenols, [4] and steroid ketones. [5] DDQ decomposes in water, but is stable in aqueous mineral acid. [6]
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 ...
A typical PCC oxidation involves addition of an alcohol to a suspension of PCC in dichloromethane. [6] [7] [8] The general reaction is: 2 [C 5 H 5 NH][CrO 3 Cl] + 3 R 2 CHOH → 2 [C 5 H 5 NH]Cl + Cr 2 O 3 + 3 R 2 C=O + 3 H 2 O. For example, the triterpene lupeol was oxidized to lupenone: [9]
Cyanuric chloride is employed as a reagent in organic synthesis for the conversion of alcohols into alkyl chlorides, [8] and carboxylic acids into acyl chlorides: [9]. It is also used as a dehydrating agent, e.g. in the conversion of amides to nitriles, [10] and for the activation of carboxylic acids for reduction to alcohols.
[2] [3] The Cornforth reagent is a strong oxidizing agent which can convert primary and secondary alcohols to aldehydes and ketones respectively. In its chemical structure and functions it is closely related to other compounds made from hexavalent chromium oxide, such as pyridinium chlorochromate and Collins reagent .
