Darstellung und molekülstruktur einer neuartigen σ-alkyl/π-Oxoallyl-tantal-verbindung

Abstract the novel tantalum compound (η 5 -C 5 H 5 )T [O⋯C(CH 3 )⋯CH C(CH 3 ) 2 ]Cl 2 has been synthesized by reductive high-pressure carbonylation of (η 5 -C 5 H 5 )TaCl 4 and subsequent treatment of the reactive intermediate with mesityl oxide. The σ-alkyl/π-oxoallyl coordination of the oxo ligand has been established by measn of X-ray diffraction methods.
