Inverted Sandwich Rh Complex Bearing a Plumbole Ligand and Its Catalytic Activity

A new possibility of a Rh­(I) complex is demonstrated. An inverted sandwich Rh­(I) complex bearing a dianionic plumbole ligand was synthesized by the reaction a dilithioplumbole with [Rh­(cod)­Cl]2. The plumbole ligand functions as a π-donor stronger than the cyclopentadienyl ligand, as evidenced by...

Description
Summary:A new possibility of a Rh­(I) complex is demonstrated. An inverted sandwich Rh­(I) complex bearing a dianionic plumbole ligand was synthesized by the reaction a dilithioplumbole with [Rh­(cod)­Cl]2. The plumbole ligand functions as a π-donor stronger than the cyclopentadienyl ligand, as evidenced by quantum-chemical calculations. The Rh­(I)−plumbole complex can be applied as a catalyst for an intramolecular [2+2+2] cycloaddition reaction of a triyne.
