Abstract

New divalent lanthanoid and alkaline earth metal complexes bearing the 1,3-bis(diphenylphosphano)cyclopentadienyl ligand have been synthesised using the redox-transmetallation protolysis (RTP) approach. From the reaction of the corresponding metal, diphenylmercury and the proligand C5H4(PPh2)2, the compounds [M(η5-C5H3(PPh2)2-1,3)2(S)] (with M=Yb, S=(thf)2 or M=Yb, Eu, Ca, Sr, Ba, S=dme) were isolated and characterised by X-ray diffraction and multinuclear NMR spectroscopy. These compounds may provide a platform for early-late heterobimetallic complexes.
