Abstract
The metathesis of functionalized and unfunctionalized acyclic olefins using catalyst compositions containing iridium and silver in a molar ration of 3 to 1.
Claims8
A method for the metathesis of acyclic olefin compounds, comprising
- reacting a starting acyclic olefin compound containing n carbon atoms, in the presence of a catalyst composition comprising compounds of Formula II and III ##STR6## wherein the molar ratio of compound III to compound II is at least 3 to 1;
- and
- wherein X is C1, Br, or I;
- R is a C.sub.1 to C.sub.10 fluorinated hydrocarbyl;
- COE is cyclooctene;
- L is cyclooctene or P(C.sub.6 F.sub.5).sub.3 ;
- and
- n is an integer between 3 and about 60;
- to yield a mixture of acyclic olefin products containing 2 to 3n carbons.
