H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides.
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 .
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.
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 ...
[1] [2] The name "Schotten–Baumann reaction conditions" often indicate the use of a two-phase solvent system, consisting of water and an organic solvent. The base within the water phase neutralizes the acid, generated in the reaction, while the starting materials and product remain in the organic phase, often dichloromethane or diethyl ether.
[1] [2] Ullman overview. Aryl-Aryl bond formation is a fundamental tool in modern organic synthesis, with applications spanning natural product synthesis, pharmaceuticals, agrochemicals, and the development of commercial dyes and polyaromatics. With over a century of history, the Ullmann reaction has been one of the first to use a transition ...
