The trifluoromethyl cation is a molecular cation with a formula of CF + 3. It is a carbocation due to its positively charged carbon atom. It is part of the family of carbenium ions, with three fluorine atoms as substituents in place of its hydrogen atoms. [1]
It has been suggested that Trifluoromethyl cation be merged into this article. ( Discuss ) Proposed since November 2024. Trifluoromethylation in organic chemistry describes any organic reaction that introduces a trifluoromethyl group in an organic compound.
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 ...
TFA is a stronger acid than acetic acid, having an acid ionisation constant, K a, that is approximately 34,000 times higher, [3] as the highly electronegative fluorine atoms and consequent electron-withdrawing nature of the trifluoromethyl group weakens the oxygen-hydrogen bond (allowing for greater acidity) and stabilises the anionic conjugate ...
An additional stabilization is achieved by the trifluoromethyl group, which acts as a strong electron-withdrawing group using the sulfur atom as a bridge. Triflates have also been applied as ligands for group 11 and 13 metals along with lanthanides. Lithium triflates are used in some lithium ion batteries as a component of the electrolyte.
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.
While the methyl group is usually part of a larger molecule, bonded to the rest of the molecule by a single covalent bond (−CH 3), it can be found on its own in any of three forms: methanide anion (CH − 3), methylium cation (CH + 3) or methyl radical (CH • 3). The anion has eight valence electrons, the radical seven and the cation six ...
The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
