Abstract
The iridium-catalyzed borylation of pyrene, using 4,4'-dimethyl-2,2'-bipyridine as the ligand, in the presence of t-BuOK, gave a mixture of 2,4,7,9-tetrakis(Bpin)pyrene (c4) and its 2,4,7,10-isomer (m4) in a 2.2:1 ratio, and the selectivity of the Ir-catalyzed borylation of pyrene is kinetically determined and can be influenced to some extent by the nature of the ligand.
