Abstract
AbstractB(C6F5)3‐catalyzed tandem double hydrofunctionalization reactions initiated by intramolecular hydroamination of unactivated alkynes are described herein. In the hydroamination/hydroallylation reaction, in situ preparation of anhydrous B(C6F5)3 from B(C6F5)3 ⋅ nH2O and the use of 2,6‐di‐tert‐butylphenol as a proton source were effective. In the hydroamination/hydrocyanation reaction, a combination of B(C6F5)3 ⋅ nH2O and H2O as the proton source provided good results.
