A non-symmetrical diboron reagent, B(pin)-B(dan), has been utilised in the Pd-catalysed borylation of aryl bromides and chlorides. Remarkably selective formation of aryl-B(dan) bonds is established. This represents a direct and efficient way to introduce masked boronic acids. The synthetic usefulness of this reaction is demonstrated in the preparation of boron-differentiated di- and polyboron compounds.

On the basis of the boron-masking strategy, new divalent cross-coupling modules have been designed for the efficient synthesis of boronsubstituted oligoarenes. The modules, i.e., monoprotected o-, m-, and p-benzenediboronic acid derivatives, undergo highly selective SuzukiMiyaura coupling with sp 2 iodides, bromides, chlorides, and triflates, affording coupling products in which the protected boronyl groups are left intact.
