Synthesis of Substituted Asymmetric Titanocenes with Bulky Substituents
Abstract:
A series of substituted cyclopentadienyllithium were prepared from exocyclic double-bond addition reaction of 6,6-dialkylfulvenes and 6,6-polymethy lenefulvenes with n-pentyllithium, 1-cyclohexenyllithium, 1,4-butylenedilithium and 1,6-hexylenedilithium, respectively. Reacting with CpTiCl3, they gave seventeen novel asymmetric titanocenes with bulky substituents. A general route for preparation of asymmetric titanocenes is herein reported.
