Claims8
A catalyst for the metathesis of olefins and functionalized olefins, which consists essentially of B.sub.2 O.sub.3 --Re.sub.2 O.sub.7 on an Al.sub.2 O.sub.3 --SiO.sub.2 substrate, wherein the B.sub.2 O.sub.3 --Re.sub.2 O.sub.7 content is from 2 to 30% by weight, based on the Al.sub.2 O.sub.3 --SiO.sub.2 content, and which catalyst further contains an organo-tin compound having the formula SnR.sub.4, wherein R is an alkyl group of from 1 to 8 carbon atoms.
