Colorless liquid Density: 1.5±0.1 g/cm 3: Melting point-110.64 ... trifluoromethanol can be prepared from trifluoromethyl hypochlorite and hydrogen chloride: CF
The first to investigate trifluoromethyl groups in relationship to biological activity was F. Lehmann in 1927. [5] An early review appeared in 1958. [6] An early synthetic method was developed by Frédéric Swarts in 1892, [7] based on antimony fluoride.
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. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group.
Two other isomers are also known: 2-trifluoromethylbenzaldehyde and 3-trifluoromethylbenzaldehyde. These compounds are derivatives of benzaldehyde with trifluoromethyl substituents. The CF 3 group enhances the electrophilicity of the formyl group and provides a label for analysis by fluorine-19 nuclear magnetic resonance spectroscopy.
Trifluoroethanol is produced industrially by hydrogenation or the hydride reduction of derivatives of trifluoroacetic acid, such as the esters or acyl chloride. [1]TFE can also be prepared by hydrogenolysis of compounds of generic formula CF 3 −CHOH−OR (where R is hydrogen or an alkyl group containing from one to eight carbon atoms), in the presence of a palladium containing catalyst ...
Trifluoracetone is also used in a synthesis of 2-trifluoromethyl-7-azaindoles starting with 2,6-dihalopyridines. The derived chiral imine is used to prepare enantiopure α-trifluoromethyl alanines and diamines by a Strecker reaction followed by either nitrile hydrolysis or reduction.
The name 1,1,1-trifluoro-N-((trifluoromethyl)sulfonyl)methanesulfonamide is also an unambiguous IUPAC-acceptable name, though the symmetry of the molecule is not apparent from this construction. See also
Trifluoroiodomethane, also referred to as trifluoromethyl iodide is a halomethane with the formula CF 3 I. It is an experimental alternative to Halon 1301 (CBrF 3 ) in unoccupied areas. [ 1 ] It would be used as a gaseous fire suppression flooding agent for in-flight aircraft and electronic equipment fires.
