4-Chloroaniline is used in the industrial production of pesticides, drugs, and dyestuffs. It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin , anilofos , monolinuron , and chlorphthalim .
4-Fluoroaniline can be prepared by the hydrogenation of 4-nitrofluorobenzene. [2] It is a common building block in medicinal chemistry and related fields. [3] For example, it is a precursor to the fungicide fluoroimide or the fentanyl analogue parafluorofentanyl. It has also been evaluated for the production of ligands for homogeneous catalysis ...
The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious. [2]
It is one of three isomeric fluoronitrobenzenes. [2] A yellow oil, it is prepared from 4-nitrochlorobenzene using the Halex process: O 2 NC 6 H 4 Cl + KF → O 2 NC 6 H 4 F + KCl. 4-Fluoronitrobenzene can be hydrogenated to give 4-fluoroaniline, [3] which is a precursor to the fungicide fluoroimide and parafluorofentanyl.
In inorganic chemistry, chlorosilanes are a group of reactive, chlorine-containing chemical compounds, related to silane (SiH 4) and used in many chemical processes. Each such chemical has at least one silicon-chlorine (Si−Cl) bond. Trichlorosilane is produced on the largest scale. The parent chlorosilane is silicon tetrachloride (SiCl 4). [1]
4-Chloro-o-toluidine (4-COT, 4-chloro-2-methylaniline) is the organic compound with the formula CH 3 C 6 H 3 Cl(NH 2). It is a colorless solid. The compound is produced as an intermediate to the pesticide chlordimeform and a precursor to some azo dyes. Production has declined after it was shown to be highly carcinogenic.
2-Chloro-6-fluorobenzaldehyde is prepared by oxidation of 2-chloro-6-fluorotolulene by chromyl chloride. [3] It reacts with sodium hydroxide to give a mixture of 2-chloro-6-fluorobenzene and 6-chlorosalicaldehyde. [4] 2-Chloro-6-fluorobenzaldehyde is used in the production of the antiseptics dicloxacillin and flucloxacillin.
CSI has been employed for the preparation of β-lactams, [4] some of which are medicinally important. Thus, alkenes undergo a [2+2]-cycloaddition to give the sulfonamide. The SO 2 Cl group can be removed simply by hydrolysis, leaving the secondary amide. [5] Other reactions of CSI: Cycloaddition to alkynes to give 1,2,3-oxathiazine-2,2-dioxide ...
