Abstract

Substantial Zr-alkyl group (R) effects on ion pair thermodynamic stability as well as on ion pair solution structure and structural dynamics are reported in the [(1,2-Me₂Cp)₂ZrR]⁺[CH₃B(C ₆F₅)₃]^- series, where R = CH₃, CH₂C(CH₃)₃, CH₂Si(CH₃)₃, and CH[Si(CH₃)₃]₂. These quantitative results underscore the effects such R moieties are likely to play in group 4 metallocene-mediated olefin polymerization catalysis.
