, p. 377 - 380 (2008/09/19)
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.
