Pentadienyl chemistry of the heavy alkaline-earth metals revisited

Abstract

Open-metallocenes of the heavy alkaline-earth metals [(η5- Pdl′)2M(thf)n] (M = Ca (1), Sr (2), n = 1; M = Ba (3), n = 2; Pdl′ = 2,4-tBu2C5H5) are readily prepared by salt-metathesis between MI2 and KPdl′ and characterized by NMR spectroscopy and X-ray diffraction studies.
