A zirconium amine bis(phenolate) catalyst that is capable of simultaneously producing both oligomers and polymers of 1-hexene was investigated. It was found that the polymer produced has more branching than the commonly encountered poly(1-hexene), su

The kinetics of 1-hexene polymerization was investigated using a previously studied zirconium amine bis-phenolate catalyst, Zr[tBu-ONTHFO]Bn2, where the effect of substoichiometric amounts of activator on the polymerization was studied to more clearl

Two non-heme manganese complexes are used in the catalytic formation of chlorine dioxide from chlorite under ambient temperature at pH 5.00. The catalysts afford up to 1000 turnovers per hour and remain highly active in subsequent additions of chlori
