The direct activation of unreactive CÀH bonds has emerged as a very active field in organic synthesis.[1] One of the best established reactions in this area is the direct borylation of arenes with bis (pinacolato) diboron (B2pin2) or pinacolborane (HBpin). After the seminal work by Smith, Hartwig, Miyaura, and their respective co-workers, this method has reached an impressive level of chemical efficiency,[2] mainly because of the introduction of the [Ir ( ...
