Pronounced effects of substituents on the iridium-catalyzed borylation of aryl C–H bonds

Abstract

Iridium trisboryl complexes containing bisphosphine and bipyridine ligands and pinacolate and catecholate substituents on boron are reported. A large difference in reactivity towards the borylation of C–H bonds is observed for this series of trisboryl complexes, and this difference is attributed to the electron-donating properties of the pinacolate vs.catecholate groups, and the steric and electronic properties of bipyridinevs.bisphosphine ligands.
