Abstract

A series of chloride-bridged unsymmetrical mixed Fe(II)-HS/Fe(II)-LS binuclear structures has been prepared and characterized. Upon activation with MAO, highly efficient catalytic polymerization of isoprene was achieved, delivering an ultra-high molecular weight (catalyst loading = 2.5 ppm, M_n = 1.8 × 10⁶ g mol⁻¹, M_w/M_n = 1.4).
