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 trifluorotoluene. [1]
4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
1,2,3-Tribromobenzene [1] [2] 1,2,4-Tribromobenzene [3] [4] 1,3,5-Tribromobenzene [5] [6] Structure Molecular formula: C 6 H 3 Br 3: Molar mass: 314.802 g/mol Appearance colorless solid CAS number [608-21-9] [615-54-3] [626-39-1] Properties Solubility in water: practically insoluble Melting point: 87.5 °C 41–43 °C 122 °C Boiling point: 274 ...
An early report (1949) describes the photochemical reaction of iodotrifluoromethane with ethylene to 3-iodo-1,1,1-trifluoropropane. [53] Reagents that have been reported for the direct trifluoromethylation of arenes are CF 3 I, CF 3 Br (thermal or photochemical), silver trifluoroacetate /TiO 2 (photochemical) and sodium ...
Monobromotoluene isomers [1] [2] [3] Common name Structure Systematic name: 1-bromo-2-methylbenzene 1-bromo-3-methylbenzene 1-bromo-4-methylbenzene Molecular formula: C 7 H 7 Br (C 6 H 4 BrCH 3) Molar mass: 171.03 g/mol Appearance colorless liquid colorless liquid white crystalline solid CAS number [95-46-5] [591-17-3]
Its melting point at -44 °C is lower than that of benzene. In contrast, the boiling points of PhF and benzene are very similar, differing by only 4 °C. It is considerably more polar than benzene, with a dielectric constant of 5.42 compared to 2.28 for benzene at 298 K. [ 4 ] Fluorobenzene is a relatively inert compound reflecting the strength ...
A sample 19F NMR spectrum of a simple organic compound. Integrations are shown under each peak. 19F NMR spectrum of 1-bromo-3,4,5-trifluorobenzene. The expansion shows the spin–spin coupling pattern arising from the para-fluorine coupling to the 2 meta-fluorine and 2 ortho proton nuclei.
Trifluoromethyl group covalently bonded to an R group. The trifluoromethyl group is a functional group that has the formula-CF 3. The naming of is group is derived from the methyl group (which has the formula -CH 3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H– CF 3, 1,1,1-trifluoroethane H ...
