ChemInform Abstract: Electrophilic Trifluoromethylation by Copper‐Catalyzed Addition of CF3‐Transfer Reagents to Alkenes and Alkynes.

Abstract: Alkenes and Alkynes. -The reaction of the hypervalent iodine reagent (I) with alkynes proceeds with complete stereoselectivity. In some cases, the yield can be increased by applying a stoichiometric amount of the copper salt. Electron-donating substituents accelerate the reaction. The reaction with mono-and disubstituted alkenes affords the expected trifluoromethyl benzoates. Iodination or bromination takes place in the reaction of (X) with stoichiometric amounts of CuI or CuBr. -(JANSON, P. G.; GHONEIM, I.; I… Show more
