title: Site-differentiated polyboron arenes prepared by direct C-H borylation and their highly selective Suzuki-Miyaura cross-coupling reactions.
abstract: Di- and polyboron (hetero)arenes, site-differentiated with MIDA boronyl (MIDA=N-methyliminodiacetic acid) and pinacolato boronyl (Bpin), were prepared by an iridium-catalyzed direct CH borylation of readily available (hetero)aryl MIDA boronates. The excellent synthetic uses of these multisite nucleophiles were demonstrated by the high-yield production of a variety of multifunctionalized poly(hetero)arenes with the highly chemoselective Suzuki-Miyaura coupling (SMC) of the Bpin moiety being an essential step.
