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

European 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 ...
