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.
在叔丁醇钾存在下，以4,4'-二甲基-2,2'-联吡啶为配体，铱催化芘的硼化反应得到了比例为2.2:1的2,4,7,9-四（硼酸频哪醇酯）芘（c4）及其2,4,7,10-异构体（m4）的混合物，并且铱催化芘硼化反应的选择性是由动力学决定的，并且在一定程度上会受到配体性质的影响。
