摘要：

Reduction of (eta(5):eta(1)-C(5)Me(4)SiMe(2)NR)TiCl2 with (n)BuLi in the presence of various 1,3-dienes yields (eta(5):eta(1)-C(5)Me(4)SiMe(2)NR)Ti(diene) complexes. The diene coordination mode (pi formally Ti(II), or metallacyclic, formally Ti(IV)) and the activity for olefin. polymerization (which can be very high) are highly sensitive to the identity of R.
