Electronic effects in iridium C-H borylations: insights from unencumbered substrates and variation of boryl ligand substituents

Experiment and theory favour a model of C-H borylation where significant proton transfer character exists in the transition state. Experiment and theory favour a model of C-H borylation where significant proton transfer character between the arene, H, and the Ir-B in the transition state.
