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 ...
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.
A more convenient alternative to SF 4 is the diethylaminosulfur trifluoride, which is a liquid whereas SF 4 is a corrosive gas: [19] [20] C 6 H 5 CHO + R 2 NSF 3 → C 6 H 5 CHF 2 + "R 2 NSOF" Apart from DAST, a wide variety of similar reagents exist, including, but not limited to, 2-pyridinesulfonyl fluoride (PyFluor) and N -tosyl-4 ...
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.
The methylchlorosilanes react with water to produce hydrogen chloride, giving siloxanes. In the case of trimethylsilyl chloride, the hydrolyzed product is hexamethyldisiloxane: 2 ((CH 3) 3 SiCl + H 2 O → [(CH 3) 3 Si] 2 O + 2 HCl. The analogous reaction of dimethyldichlorosilane gives siloxane polymers or rings: n (CH 3) 2 SiCl 2 + n H 2 O ...
The Suzuki reaction or Suzuki coupling is an organic reaction that uses a palladium complex catalyst to cross-couple a boronic acid to an organohalide. [1] [2] [3] It was first published in 1979 by Akira Suzuki, and he shared the 2010 Nobel Prize in Chemistry with Richard F. Heck and Ei-ichi Negishi for their contribution to the discovery and development of noble metal catalysis in organic ...
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 .
An easy example is that of CFC-12, which gives: 90+12=102 -> 1 carbon, 0 hydrogens, 2 fluorine atoms, and hence 2 chlorine atoms resulting in CCl 2 F 2. The main advantage of this method of deducing the molecular composition in comparison with the method described in the paragraph above is that it gives the number of carbon atoms of the molecule.
