A derivative of trifluorotoluene, 3-aminobenzotrifluoride, is the precursor to the herbicide fluometuron. [3] It is synthesized via nitration followed by reduction to meta-H 2 NC 6 H 4 CF 3. This aniline is then converted to the urea. Flumetramide (6-[4-(trifluoromethyl)phenyl]morpholin-3-one), a skeletal muscle relaxant, is also prepared from ...
Benzonitrile is the chemical compound with the formula C 6 H 5 (CN), abbreviated PhCN. This aromatic organic compound is a colorless liquid with a sweet bitter almond odour. It is mainly used as a precursor to the resin benzoguanamine .
Typical nitrile ligands are acetonitrile, propionitrile, and benzonitrile.The structures of [Ru(NH 3) 5 (NCPh)] n+ have been determined for the 2+ and 3+ oxidation states. Upon oxidation the Ru-NH 3 distances contract and the Ru-NCPh distances elongate, consistent with amines serving as pure-sigma donor ligands and nitriles functioning as pi-acceptors.
TFA is the precursor to many other fluorinated compounds such as trifluoroacetic anhydride, trifluoroperacetic acid, and 2,2,2-trifluoroethanol. [4] It is a reagent used in organic synthesis because of a combination of convenient properties: volatility, solubility in organic solvents , and its strength as an acid. [ 7 ]
[2] [3] This synthesis route was first described by Frédéric Swarts in 1922. [4] Trifluoroacetonitrile can also be produced by reacting 1,1,1-trichloro-2,2,2-trifluoroethane and ammonia at 610 °C. [5]
The Thiele tube is heated; dissolved gases evolve from the sample first. Once the sample starts to boil, heating is stopped, and the temperature starts to fall. The temperature at which the liquid sample is sucked into the sealed capillary is the boiling point of the sample. [2] [3] [4] [5]
Thiazyl fluoride, NSF, is a colourless, pungent gas at room temperature and condenses to a pale yellow liquid at 0.4 °C. [1] Along with thiazyl trifluoride, NSF 3, it is an important precursor to sulfur-nitrogen-fluorine compounds. It is notable for its extreme hygroscopicity.
4-Cyano-3-(trifluoromethyl)aniline, also known as 4-amino-2-(trifluoromethyl)benzonitrile, is a cyanated and trifluoromethylated derivative of aniline. It is the starting material in one of the chemical syntheses of the nonsteroidal antiandrogen bicalutamide .
