SYNTHESIS AND CHARACTERIZATION OF SOME FERROCENE-CONTAINING TELLUROETHER LIGANDS - CRYSTAL-STRUCTURE OF 1,1'-BIS(PHENYLTELLURO) FERROCENE

Abstract

A series of five monodentate ferrocene tellurium ligands of the type Fe(C5H5)(C(5)H(4)TeR) and five bidentate 1,1'-disubstituted ferrocene tellurium ligands of the type Fe(C(5)H(4)TeR)(2) (R=Me, (n)Bu, C6H5, p-MeOC(6)H(4), p-EtOC(6)H(4)) has been prepared by the reaction of 1,1'-dilithioferrocene with the appropriate ditellurides R(2)Te(2). The ligands have been characterized by their elemental analyses, H-1 and C-13 NMR spectra, mass spectra and cyclic voltammetry studies. The structure of Fe(C5H4TeC6H5)(2) has been determined by single-crystal X-ray diffraction study.
