α,α,α-Trifluoro-p-tolualdehyde - Reference Information
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Synthesis method | Using p-trifluoromethylaniline as raw material, p-trifluoromethylbenzaldehyde is prepared by diazotization, oxime, and hydrolysis. The yield is 35.9%. The mixed solution of halogenated hydrocarbon additive and p-trifluoromethylchlorobenzene is slowly added to the tetrahydrofuran solution impregnated with magnesium chips to synthesize the Grignard reagent of p-trifluoromethylchlorobenzene; N,N-dimethylformamide is added to the Grignard reagent of p-trifluoromethyl chlorobenzene to react to obtain this product. |
| Use | Kinetic research reagents for Wittig reactions and asymmetric synthesis reactions of alcohols |
