4,7-Dichloroquinoline was first reported in a patent filed by IG Farben in 1937. [2] However, its synthesis was not investigated in detail until chloroquine was developed as an antimalarial drug. [ 3 ] : 130–132 A route to the intermediate starting from 3-chloroaniline was developed by chemists at Winthrop Chemical Co .
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 ...

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.
