The synthesis, characterization, and ethylene polymerization behavior of novel RuIV(η3:η3-C10H 16)(OPO) (OPO = bis(arenesulfonato)phosphine) complexes is reported here. Upon activation with AlMe3-depleted methylaluminoxane (dMAO), the Ru(IV) precursors were able to produce polyethylene with activities up to 1182 h-1 turnover frequency (TOF). The polymers were highly linear with a low degree of branching (p = 289 kg mol-1) with a bimodal molecular weight distribution. The polymerization activity increased with decreasing donor strength of the OPO ligand.
