Facile insertion of carbodiimides, R1N=C=NR3, into a Ti-CMe bond of (C5R5)TiMe3 (R = H and Me) (2a and 2b, respectively) in pentane solutions at 25 °C provides a wide range of derivatives of (C5R5)TiMe2-[NR1C(Me)NR3] (1) in high yield. Low barriers to racemization (≤15 kcal mal-1) have been determined for derivatives of 1 where R1 ≠ R3, and further, a preliminary screen has found some of these to be Ziegler-Natta catalyst precursors for the polymerization of ethylene upon activation with methylaluminoxane.
