Reduction of (η5:η1-C5Me4SiMe2NR)TiCl2 with nBuLi in the presence of various 1,3-dienes yields (η5:η1-C5Me4SiMe2NR)Ti(diene) complexes. The diene coordination mode (π, 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.
