Abstract: Abstract: Iridium-catalyzed borylation of phenacenes with bis(pinacolato)diboron proceeds either in an edge-selective manner for diborylation or an edge/side-selective manner for tetraborylation. Multiply borylated [n]phenacenes (n =3–5) were synthesized in reasonable yields. [Copyright &y& Elsevier]
