Metal-Free Arene and Heteroarene Borylation Catalyzed by Strongly Electrophilic Bis-boranes

Abstract

The geminal chelate bis-borylalkanes 4 and 5 featuring strongly electrophilic B(C6F5)2 and B(C6F5) groups, respectively, serve as efficient catalysts for the borylation of arenes and heteroarenes. The borylation reactions proceed under mild conditions with liberation of dihydrogen.
