Coexistence of Metallocene Cations and Anions

Journal of the American Chemical Society
We report the synthesis and structural characterization of the rhodocene anion [Rh(C5Me5)(C5(CF3)5)]− [1]− as the [Co(C5Me5)2]+ salt, representing an unprecedented coexistence of metallocene cations and anions in different oxidation states. [Co(C5Me5)2]+ [1]− was synthesized by the reduction of the rhodocenium cation [Rh(C5Me5)(C5(CF3)5)][BF4] ([1 ...

Control of Polymer Particle Size by Supported Metallocene Catalysts

, 2013
[[abstract]]By utilizing a pre-mixing method, we can prepare a supported metallocene catalyst producing a polyethylene of larger granular size and containing fewer fine particles than that prepared by the conventional adsorption of metallocene on a MAO ...
