Abstract
Official abstract text for this publication.
A novel chelated ruthenium-based metathesis catalyst bearing an N-2,6-diisopropylphenyl group is reported and displays near-perfect selectivity for the Z-olefin (>95%), as well as unparalleled TONs of up to 7,400, in a variety of homodimerization and industrially relevant metathesis reactions. This derivative and other new catalytically-active species were synthesized using an improved method employing sodium carboxylates to induce the salt metathesis and C—H activation of these chelated complexes. All of these new ruthenium-based catalysts are highly Z-selective in the homodimerization of terminal olefins.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for preparing a macrocyclic compound comprising reacting a C—H activated metathesis catalyst represented by formula 9 with a diene, wherein the diene is represented by the formula 18a and the macrocyclic compound is represented by the formula 18 2. A process for preparing a macrocyclic compound comprising reacting a C—H activated metathesis catalyst represented by formula 9 with a diene, wherein the diene is represented by the formula 19a and the macrocyclic compound is represented by the formula 19 3. A process for preparing a macrocyclic compound comprising reacting a C—H activated metathesis catalyst represented by formula 9 with a diene, wherein the diene is represented by the formula 20a and the macrocyclic compound is represented by the formula 20
