Contributions to the chemistry of transition metal alkyl compounds. 56. 2‐(Dimethylaminomethyl)ferrocenyl derivatives of titanium and zirconium – limits of chelating interactions

Abstract

AbstractThe new paramagnetic (η5‐C5H5)2Ti(FcN) III (FcN = 2‐[dimethylaminomethyl]‐ferrocenyl) and diamagnetic (η5‐C5H5)2Zr(1‐Camph)(FcN) IV (1‐Camph = 1‐Camphenyl) complexes were prepared and characterized by spectra and magnetic measurements. The crystal and solid phase molecular structures of (η5‐C5H5)2M(FcN)2 (M = Ti I and Zr II) compounds were determined by single crystal X‐ray diffraction. An MC, N chelation of the (dimethylaminomethyl)ferrocenyl ligand was detected at compounds III (solid phase) and IV (solution), while such interaction fails at complexes I and II in crystalline phase.
