TL;DR: In this article, the catalysts for the polymerization of propylene and ethylene were investigated by using corresponding racemic, ethylene-bridged analogues (5a, X = H; 5b and X = CH{sub 3}; 5d, X= OCH{sub 2}).

TL;DR: In this article, the authors used the Flory-Schulz theory to calculate the ratio of rate coefficients for propagation (k(p)) and termination (k (t)) for a double-ended dagger p - DELTA-G doubleended dagger t)298K, which was calculated as -19 (3) and -14 (4) kcalmol-1 for N,N-dimethylaniline.

TL;DR: In this paper, a dippb ligand (dippb = 1,4-bis(diisopropylphosphino)butane) coordinated Pd complex was used for direct vinylation of aryl chlorides.

TL;DR: In this paper, GPC analysis shows that poly(1)-sub n) polymers have low polydispersities (M{sub w}/M{ sub n} {le} 1.25) and values for M{sub n} that increase linearly with the amount of monomer employed.

TL;DR: In this article, the authors describe the chemical preparation of water-soluble phosphine complexes of ruthenium (II) and rhodium (I) using X-ray crystallography.

TL;DR: In this article, the authors explored the possibilities offered by the modification of thiolato bridges in dinuclear rhodium complexes on the selective hydroformylation of cylic vinyl and allyl ethers.

TL;DR: In this article, a simplified method for obtaining rate constants from dynamic NMR experiments in which the exchange processes are defined by more than a single rate-limiting step is described, which can be used in the construction of kinetic (Kubo-Sack) matrices.

TL;DR: In this paper, the coordination strength of these anions within the cobalt complexes was investigated for the polymerization and copolymerization of ethylene and α-olefins.

TL;DR: In this article, the aryl group is characterized by X-ray diffraction and the ligand Me{sub 2}NCH{sub 6}F{sub 5} is activated than a C-F.
