TL;DR: In this article, a model was proposed which accounts for both the observed metathesis and the cis-trans isomerisation, as measured by the relative amounts of the various olefins produced at low conversion from the reaction of cis-pent-2-ene on a tungsten catalyst.

TL;DR: In this article, the effect of the structure of olefins on their reactivity has been studied in terms of three variables: length of the chain between the aromatic ring and the double bond, substituent effects at the double-bond, and substituents effects on the aromatic chain.

TL;DR: In this article, a comparison of the WCl6-metal alkyl systems (Bu4Sn, Et2Zn, Et3Al, and BuLi) was carried out in the metathesis of 2-heptene in benzene.

TL;DR: Improved homogeneous metathesis catalysts are obtained by the use of a trivalent phosphorus modifying agent with a cocatalyst comprised of tungsten hexachloride and an organotin compound as mentioned in this paper.
Abstract: Improved homogeneous metathesis catalysts are obtained by the use of a trivalent phosphorus modifying agent with a cocatalyst comprised of tungsten hexachloride and an organotin compound. These modified catalyst systems give significantly increased conversions and excellent product selectivity when used for olefin metathesis.

TL;DR: Pyridinepentacarbonylmolybdenum with ethylaluminium dichloride and tetrabutylammonium chloride constitute a catalyst system for the metathesis of terminal olefins as discussed by the authors.
Abstract: Pyridinepentacarbonylmolybdenum with ethylaluminium dichloride and tetrabutylammonium chloride constitute a catalyst system for the metathesis of terminal olefins; evidence for a co-ordinated carbene-initiated process is presented, and the nature of the co-ordinated carbene formed initially is found to be solvent dependent.
