Olefin metathesis catalyst

Metathesis Enables Our Next-Generation Thermoset Resins Olefin Metathesis Olefin metathesis is a chemical reaction in which a molecule with a pair of carbon-carbon double bonds, known also as olefins or hydrocarbons, come together and exchange carbon atoms with one another, forming new value-added molecules in the process. Represented in this example, two groups of symmetrical olefins shown in pairs of two blue and two green carbon groups are transformed into two pairs of new non-symmetrical olefins shown with one blue and one green carbon group per olefin. Low catalyst loadings, solvent-free conditions, and high yielding processes make olefin metathesis both economical and manufacturing-ready. What makes olefin metathesis cost-effective also makes it green.

The selective activation of one C−F bond (single activation) of the CF 3 group on cyclopropanes was achieved for the first time. When (trifluoromethyl)cyclopropanes were treated with arenes, allylsilanes, silyl enol ethers, or hydrosilanes in the presence of Me 2 AlCl, fluoride elimination and the subsequent ring opening proceeded to afford 4,4‐difluorohomoallylated products.

Reversible addition–fragmentation chain transfer (RAFT) radical polymerization has, since its discovery by CSIRO, evolved into an extremely powerful synthetic tool for polymer chemists.

Industries Overview

This catalyst is commonly known as the 2 nd Generation Grubbs Catalyst, and along with the 1 st Generation Grubbs Catalyst is one of the most widely-used homogenous metathesis catalysts.

It provides a distinct increase in activity in all olefin metathesis reactions while maintaining functional group tolerance similar to the 1 st generation system. As a consequence, it generally requires lower.

As a consequence, it generally requires lower. In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon–carbon double bond. The words alkene and olefin are often used interchangeably (see nomenclature section below). Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n.
