Synthesis and crystal structures of dimethylsilylene-bridged (amidocyclopentadienyl)dichlorotitanium(IV) complexes with various substituents on the cyclopentadienyl ligands

Abstrakt

(Amidocyclopentadienyl)dichlorotitanium(IV) complexes of the general formula, [TiCl2{h5:h1(N)-C5(1-SiMe2Nt-Bu-2,3,4-Me3-5-R)}], where R = H (6b), Ph (6c), 4-fluorophenyl (6d) and 1-methylallyl (6e) were synthesized and characterized by spectral methods. Solid-state structure of [TiCl2{h5:h1(N)-C5Me4(SiMe2Nt-Bu)}] (6a) and 6d determined by single-crystal X-ray diffraction showed th at variation of the ring substituent R has only a negligible effect(6a) and 6d determined by single-crystal X-ray diffraction showed that variation of the ring substituent R has only a negligible effect on the molecular structure of the complexes.
