An unsymmetrical binuclear iminopyridine-iron complex and its catalytic isoprene polymerization

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...

Summary: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 × 10 6 g mol −1 , M w / M n = 1.4). A series of chloride-bridged unsymmetrical Fe( ii )-HS/Fe( ii )-LS binuclear complexes has been developed, which can efficiently catalyze isoprene polymerization with 0.00025 mol% loading, delivering ultra-high molecular weight polymers.
