Dinuclear Group 4 Metallocene Catalysts of the Type [(Cp2M)2(μ‐Me)(μ‐C2R)]: Structure‐Activity Relationships in Ethylene Polymerization

open access: yesChemistry – A European Journal, EarlyView.
Homo‐ and heterodinuclear group 4 metallocene complexes of the type [(Cp2M)2(μ‐Me)(μ‐C2R)] (M = Ti, Zr) are active catalysts for the polymerization of ethylene in the presence of aluminium‐free activators. The catalytically active species are proposed to have dinuclear character and depending on the type of activator, unique reactivity was observed ...

Redox‐Active Bisphosphines Based on a W(II)‐Propargyl Complex Backbone

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Three bisphosphine ligands based on tungsten(II) propargyl‐type alkyne complexes were synthesized and characterized. The methanolate derivative was used as a metalla‐ligand for the preparation of a binuclear bisphosphine‐κ2‐PdCl2 complex. In both cases, IR spectroelectrochemistry (IR‐SEC) measurements revealed a successive process following oxidation ...
