Author affiliations

Abstract

The borenium cations [(C7H5N2Ad)B(C6F5)2][AlCl4/Al2Cl7] 2a, and [(C7H5N2Me)B(C6F5)2][B(C6F5)4] 2b were prepared and are shown to feature a high Lewis acidity, the capability to activate hydrogen and to effect the 1,1-carborations of terminal and internal alkynes under mild conditions.
