Chemical Properties
4-Iodobenzotrifluoride is a clear red to pink liquid with has the odor of halogenated benzene, is insoluble in water, and is miscible with benzene, toluene, ethanol, ether, halogenated hydrocarbons, etc.
Uses
4-Iodobenzotrifluoride may be employed as substrate with electron-deficient aromatic ring, during Mizoroki-Heck reaction with acrylic acid, to afford 4-trifluoromethylcinnnamic acid. It undergoes aminocarbonylation in DMF using phosphoryl chloride to give N,N-dimethyl-(4-trifluoromethyl)benzamide.
Preparation
Synthesis of 4-Iodotrifluorotoluene: Prepared by diazotization and iodination of 4-aminobenzotrifluoride or 4-Iodobenzotrifluoride is prepared by direct iodination with trifluorotoluene as raw material.
Application
The fluorine atom in the molecular structure of 4-iodotrifluorotoluene makes it have special activity. It is an important pesticide and pharmaceutical intermediate. It can be used as the intermediate of the insecticide fipronil and used for the synthesis of diphenyl ethers containing fluorine herbicide.
General Description
4-Iodobenzotrifluoride undergoes aminocarbonylation in DMF using phosphoryl chloride to give
N,N-dimethyl-(4-trifluoromethyl)benzamide. Mechanism of the copper-free Sonogashira cross-coupling reaction of 4-iodobenzotrifluoride with differently
para-substituted phenylacetylenes has been investigated.
