Synthese und Charakterisierung ruthenocen- und osmocenhaltiger Hetero-Oligometallocene / Synthesis and Characterization of Hetero-Oligometallocenes Containing Ruthenocene and Osmocene

Abstract

Improved syntheses of ruthenocene (Ruc) and osmocene (Osc) are described. These lithiated metallocenes (RucLi 1-3 and OscLi 1-3 ) react with cobaltocenium-hexafluorophosphate (Coc + PF 6 - ) to give the corresponding oligometallocenes Coc + —RucPF 6 - (1), 1,1′-(Coc + ) 2 -Ruc(PF 6 ) 2 (2), Coc + —OscPF 6 - (4), and 1,1′-(Coc+) 2 —Osc(PF 6 ) 2 (5). The products were characterized by IR, MS, NMR and elemental analysis.
