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 ...
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 3 C – CF 3, and hexafluoroacetone F 3 C –CO– CF 3.
4-Trifluoromethylbenzaldehyde is the organofluorine compound with the formula CF 3 C 6 H 4 CHO. Two other isomers are also known: 2-trifluoromethylbenzaldehyde and 3-trifluoromethylbenzaldehyde. These compounds are derivatives of benzaldehyde with trifluoromethyl substituents.
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 .
Compared to the methyl radical the CF 3 radical is pyramidal (angle 107.8 °C ) with a large inversion barrier, electrophilic and also more reactive. In reaction with styrene it is 440 times more reactive. [52] An early report (1949) describes the photochemical reaction of iodotrifluoromethane with ethylene to 3-iodo-1,1,1-trifluoropropane. [53]
Its pK a value in water cannot be accurately determined but in acetonitrile it has been estimated as −0.10 and in 1,2-dichloroethane −12.3 (relative to the pK a value of 2,4,6-trinitrophenol (picric acid), anchored to zero to crudely approximate the aqueous pK a scale [2]), making it more acidic than triflic acid (pK a MeCN = 0.70, pK a DCE ...
Trifluoroiodomethane contains carbon, fluorine, and iodine atoms. Although iodine is several hundred times more efficient at destroying stratospheric ozone than chlorine, experiments have shown that because the weak C-I bond breaks easily under the influence of water (owing to the electron-attracting fluorine atoms), trifluoroiodomethane has an ozone depleting potential less than one ...
Trifluoromethyltrimethylsilane (known as Ruppert-Prakash reagent, TMSCF 3) is an organosilicon compound with the formula CF 3 Si(CH 3) 3. It is a colorless liquid. It is a colorless liquid. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group .
