The effect of a series of hydrotris(pyrazolyl)borate ligands (Tpx) in the regioselectivity of the catalytic functionalization of the secondary carbon-hydrogen bonds of hexane with ethyl diazoacetate and TpxCuL as the catalysts has led to the definition of the relative steric parameter SPR. The validity of the parameter has been assessed upon its correlation with the regioselectivity observed in several transformations (olefin cyclopropanation, C−H functionalization, C−H amidation), in all cases a good degree of fitting being observed.
