The substituted half-sandwich titaconece with bulky alkoxyl group [CpTiC1〓 or CpTi 〓] or indene ring can not be fluorinated by BF〓·Et〓O under the selected condition, but still coordinates with the BF〓, this coordination then enhances the steric effect that stabilizes the precursor and hinders the reduction of the Ti to the Ti species, reflected in the decrease in polymerization activity.
但是这个转化受主催化剂分子的空间位阻和聚合反应温度的影响,当主催化剂为大位阻的烷氧基取代茂钛络合物或茚钛络合物时,在一般的聚合温度下BF〓不能对它们进行氟化,但可以和其中的OR配位,这种配位进一步加剧了空间位阻,从而阻碍了活性中心的形成,导致催化活性的下降。
