Highly selective catalytic trans-hydroboration of alkynes mediated by borenium cations and B(C(6)F(5))(3)
The trans-hydroboration of terminal alkynes mediated by borenium cations [NHC(9-BBN)](+) (NHC = N-heterocyclic carbene, 9-BBN = 9-borabicyclo(3.3.1)nonane) exclusively affords Z-vinylboranes. NHCs and chelating dialkyl substituents on the borenium cation and “non”-basic anions were essential to prec...
