Redox-active phosphines: synthesis and crystal structures of palladium(ii) complexes of a metallaphosphine in two different oxidation states†
Abstract
The redox-active metallaphosphine [Fe(dppe)(η5-C5Me5)(CC–PPh2)] reacts with [Pd(1,5-cod)Cl2] to give mono- and bis-phosphine coordinated palladium centres as a function of stoichiometry, and these complexes provide a stable redox-active platform which allows reversible one-electron {Fe(II)→Fe(III)+} oxidations within the palladium coordination sphere.
