Olefin Metathesis
Olefin metathesis has emerged as a key method for synthesizing long and complex alkenes through highly efficient and selective catalytic reactions. We are dedicated to helping you explore new frontiers with an innovative and expanding portfolio of olefin metathesis products. To achieve this goal, we have partnered with Umicore PMC to offer a wide range of olefin metathesis catalysts for chemical synthesis. Developed by Nobel Laureate Prof. Robert H. Grubbs and his team, these catalysts are known for their outstanding performance, enabling robust alkene conversions. Our exclusive collaboration provides you with direct access to Umicore’s Grubbs Catalyst® technology with Umicore license rights included in the listed product price. Explore our offerings and discover how we can support you in achieving your metathesis goals.

Selected Best Metathesis Practices
- Consider Concentration: Run cross-metathesis reactions concentrated and macrocyclization reactions diluted.
- Oust Oxygen: Degassing reactions with an inert gas prior to adding a Grubbs catalyst can improve catalyst lifetime and efficiency. Degassing during the reaction has the added benefit of efficiently removing ethylene from metathesis reactions where it is generated.
- Solvent Selection: Consider solubility and use non-coordinating solvents, when possible, such as cyclohexane, toluene, or dichloromethane.
