compatible with this reaction. A plausible mechanism has been
proposed based on control experiments and a KIE study. We
believe this transition-metal-like property of boryl radicals can
provide new opportunities for transition-metal-free C−H
functionalizations. Further mechanistic studies and evaluations
of the applicability of this ligand-exchange strategy are currently
underway in our laboratory and will be published in due course.
