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.
