We evaluate the balance of steric and electronic effects in the site selectivity of the binding of [Rh(Me5Cp)]+ ([RhCp·]+) to the three possible coordination sites of the polyaromatic hydrocarbon (PAH) hexa-tert-butyl-hexa-peri-hexabenzocoronene (HBBC). We find that despite the close proximity of sterically demanding tert-butyl groups to the methyl groups of the Cp* ligand, the extent of steric repulsion is minor compared to electronic interaction from bond formation and that the site selectivity is best explained in terms of the electronics of the (poly) aromatic system. This is in contrast to previous investigations on similar systems with a COD ligand where steric influence has been shown to dominate selectivity.

This review summarizes recent advances in C–S and C–Se formations via transition metal-catalyzed C–H functionalization utilizing directing groups to control the site-selectivity.
