Structure of the chloromethyl group. In organic chemistry, the chloromethyl group is a functional group that has the chemical formula −CH 2 −Cl. The naming of this group is derived from the methyl group (which has the formula −CH 3), by replacing one hydrogen atom by a chlorine atom. Compounds with this group are a subclass of the ...
Benzyl chloride is prepared industrially by the gas-phase photochemical reaction of toluene with chlorine: [3] C 6 H 5 CH 3 + Cl 2 → C 6 H 5 CH 2 Cl + HCl. In this way, approximately 100,000 tonnes are produced annually. The reaction proceeds by the free radical process, involving the intermediacy of free chlorine atoms. [4]
The structure of xylylene dichloride is characterized by an benzene ring with two chloromethyl groups and four hydrogen atoms bound to it. [4] The chloromethyl groups can be located on different sites on the ring, leading to a few different possible forms. These forms are: [3] o-xylylene dichloride: 1,2-bis(chloromethyl)benzene
A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...

Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.
TPCK is observed covalently bound in the active site of Caspase 3 in the crystal structure of the complex solved in 2010. [2] The chloromethyl group reacts with the active site cysteine to form a covalent bond with the loss of the chlorine. TPCK is chosen for the chemical labelling of active histidine in enzyme analysis.
Trichlorobenzene (TCB) may refer to any of three isomeric chlorinated derivatives of benzene with the molecular formula C 6 H 3 Cl 3. They differ by the positions of the chlorine atoms around the ring: 1,2,3-Trichlorobenzene; 1,2,4-Trichlorobenzene; 1,3,5-Trichlorobenzene
