Abstract

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 [Cp2Zr(η2‐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.
