Synthesis of Telechelic Polyisoprene via Ring-Opening Metathesis Polymerization in the Presence of Chain Transfer Agent [PDF]
Telechelic polyisoprene was synthesized via the ring-opening metathesis polymerization (ROMP) of 1,5-dimethyl-1,5-cyclooctadiene (DMCOD) in the presence of cis-1,4-diacetoxy-2-butene as a chain transfer agent (CTA).

Relevance of cis- and trans-dichloride Ru intermediates in Grubbs-II olefin metathesis catalysis (H(2)IMesCl(2)Ru=CHR) [PDF]
Using density functional theory with the B3LYP and M06 functionals, we show conclusively that the (H2IMes)(Cl)2Ru olefin metathesis mechanism is bottom-bound with the chlorides remaining trans throughout the reaction, thus attempts to effect diastereo ...

DFT Investigation into the Role of Conventional and Ionic Liquids as Solvents in Olefin Metathesis
The effects of conventional and ionic liquids on the metathesis of olefin have been investigated by means of quantum chemical calculations to establish the factors favouring the metathesis of olefin in ionic liquid. The results suggest that ionic liquids

Conformations of N-Heterocyclic Carbene Ligands in Ruthenium Complexes Relevant to Olefin Metathesis [PDF]
The structure of ruthenium-based olefin metathesis catalyst 3 and model π-complex 5 in solution and in the solid state are reported. The N-tolyl ligands, due to their lower symmetry than the traditional N-mesityl substituents, complicate this analysis ...

Probing the Electronic Structure of Spectator Oxo Ligands by 17O NMR Spectroscopy
Spectator oxo ligands are ubiquitous in catalysis, in particular in olefin epoxidation and olefin metathesis. Here we use computationally derived 17O NMR parameters to probe the electronic structure of spectator oxo ligands in these two reactions.
