Hydrosilyl Group-directed Iridium-catalyzed <i>peri</i>-Selective C–H Borylation of Ring-fused (Hetero)Arenes

Abstract

The iridium-catalyzed direct C–H borylation of ring-fused (hetero)arenes afforded borylated products in a peri-selective manner, directed by a proximal hydrosilyl group. Further selective transformations of the boryl and silyl groups enabled the synthesis of various multisubstituted (hetero)arenes, such as 1,8-disubstituted naphthalenes and 3,4-diarylindole.
