WebMay 25, 2011 · Catalysed C sp3 −F and C sp3 −CF 3 bond formation. Organic molecules with fluorine atoms or trifluoromethyl groups bonded to sp3 -hybridized carbon (C sp3) … Various methods exist to introduce this functionality. Carboxylic acids can be converted to trifluoromethyl groups by treatment with sulfur tetrafluoride and trihalomethyl compounds, particularly trifluoromethyl ethers and trifluoromethyl aromatics, are converted into trifluoromethyl compounds by treatment with antimony trifluoride/antimony pentachloride (the Swarts reaction). Another route to trifluoromethyl aromatics is the reaction of aryl iodides with trifluoromethyl copp… WebSubstituents and their Directing Effects in EAS Reactions. Electron donating groups (D) direct the reaction to the ortho- or para-position, which means the electrophile substitutes for the hydrogen on carbon 2 or carbon 4 relative to the donating group.
