Sticky counterions: Low-temperature kinetic NMR studies were performed to determine ΔH≠ and ΔS≠ values for the insertion of a single 2-methyl-1-heptene molecule into a Zr-C bond of [Cp 2Zr(I·2-CH2NMePh)][X] (1a: X -=MeB(C6F5)3-, 1b: B(C6F5)4-) in [D8]toluene and a 1:1 mixture of [D8]toluene and [D5]chlorobenzene. Both activation parameters critically depend on the interplay of the counterion and the solvent. Copyright
