According to Ogawa and Curran, trifluorotoluene is similar to dichloromethane in standard acylation, tosylation, and silylation reactions. [4] The dielectric constants for dichloromethane and trifluorotoluene are 9.04 and 9.18, respectively, indicating similar solvating properties.
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. In this reaction benzotrichloride was reacted with SbF 3 to form PhCF 2 Cl and PhCF 3.
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 ...
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.
