Purification is challenging because the individual isomers have similar properties. The 2,6 and 3,5 isomers do not form acceptably from toluene or chlorotoluenes, so these isomers are prepared by indirect methods. For example, 2,6-dichlorotoluene can be prepared by chlorination of 4-toluenesulfonyl chloride followed by desulfonation. [1]
2,6-Dichloroquinone-4-chloroimide (Gibbs reagent) is an organic compound used as an colorimetric indicator to detect phenolic compounds. [1] Upon reaction with phenol itself, 2,6-dichlorophenolindophenol is formed, [ 2 ] a chemical that is used as a redox indicator .
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 ...
More conveniently, the compound is prepared by the reaction of hydrated iridium trichloride and pentamethylcyclopentadiene in hot methanol, from which the product precipitates [1] 2 Cp*H + 2 IrCl 3 (H 2 O) 3 → [Cp*IrCl 2] 2 + 2 HCl + 6 H 2 O. The Ir-μ-Cl bonds are labile and can be cleaved to give a variety of adducts of the general formula ...
2,6-Dichlorophenol is a compound with formula C 6 H 3 Cl 2 OH. It is one of the six isomers of dichlorophenol. It is a colorless solid. Its pK a is 6.78, which is about 100x more acidic than 2-chlorophenol (8.52) and 1000x more acidic than phenol itself (9.95). [3]
1,3-Dichloro-2-nitrobenzene is an organic compound with the formula C 6 H 3 Cl 2 (NO 2). It is one of several isomeric dichloronitrobenzenes. It is an off-white solid that is soluble in conventional organic solvents. The compound can be prepared by oxidation of 2,6-dichloroaniline using peroxytrifluoroacetic acid. [1]
