Unsaturated structures in polyolefin polymers are important in many respects. In this work, new vinyl and vinylidene structures were identified in poly(ethylene-co-1-octene) copolymers. The combina...

The half-sandwich imido tantalum dichloride (η5-C5Me4H)Ta(NtBu)Cl2 is prepared directly from the reaction of the neutral constrained-geometry ligand Me2Si(C5Me4H)(tBuNH) and TaCl5 in refluxing tolu...

Reaction between M(C6F5)3 (M = B, Al) and AlR3 in hydrocarbons leads to facile aryl/alkyl group exchange and formation of aluminum dimers, while reaction of (perfluoroaryl)boranes B(C6F5)3 and B(C12F9)3 with AlR3 (R = Me, Et, octyl) or GaMe3 in ether

Recently, a high temperature 10 mm cryoprobe was developed. This probe provides a significant sensitivity enhancement for (13)C NMR of polyolefins at a sample temperature of 120-135 degrees C, as compared to conventional probes. This greatly increase
