Chemical and Electrochemical Oxidation of Diferrocenyltelluride

Abstract The halogenation of diferrocenyltelluride, Fc 2 Te, with XeF 2 , PhICl 2 and I 2 afforded the diferrocenyltellurium dihalides Fc 2 TeX 2 (X=F, Cl, I). Halide exchange of Fc 2 TeCl 2 with KBr yielded Fc 2 TeBr 2 . The oxidation of Fc 2 Te with NO[SbF 6 ] and K[B(C 6 F 5 ) 4 ] provided the triferrocenyltelluronium salt [Fc 3 Te][B(C 6 F 5 ) 4 ] and the dinuclear nitrosyl iron complex Fe 2 (μ‐TeFc) 2 (NO) 4 . The new compounds were comprehensively characterized by multinuclear NMR spectroscopy ( 125 Te, 19 F, 13 C, 1 H), UV/vis absorption spectroscopy, cyclic voltammetry, LIFDI‐TOF mass spectrometry and single crystal X‐ray diffraction.
