The modules, i.e., monoprotected <i>o</i>-, <i>m</i>-, and <i>p</i>-benzenediboronic acid derivatives, undergo highly selective Suzuki−Miyaura coupling with sp<sup>2</sup> iodides, bromides, chlorides, and triflates, affording coupling products in which the protected boronyl groups are left intact.
