Stereoselective syntheses of spirane bridged semi-titanocenes
Bjornstad, Vidar,Undheim, Kjell
, p. 962 - 970 (2008/09/21)
The synthesis of bidentate cyclopentadienyl-alkoxide ligands and their complexation to titanium are described. The focus has been on methodology for stereoselective synthesis of ansa half-sandwich titanocenes with rigid C 2- and C3-b
