Rapid Access to Dimethylcyclopentadienyltitanium(IV) Amidinate, (C5R5)TiMe2[NR1C(R2)NR3] (R = H and Me; R2 = Me), Libraries
摘要:
Facile insertion of carbodiimides, (RN)-N-1=C=NR3, into a Ti-C-Me bond of (C5R5)TiMe3 (R = H and Me) (2a and 2b, respectively) in pentane solutions at 25 degrees C provides a wide range of derivatives of (C5R5)TiMe2[(NRC)-C-1(Me)NR3] (1) in high yield. Low barriers to racemization (less than or equal to 15 kcal mol(-1)) have been determined for derivatives of 1 where R-1 not equal R-3, 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.
This application relates to triacylglycerol oligomers derived from the metathesis of natural oils. These oligomers are structure controlled dimers and quatrimers, and the effect of saturation, molecular size, and positional isomerization are also described herein.
