Tungsten and Molybdenum Alkylidene Catalysts for Olefin Metathesis
Background
Brief Description
Professors Richard Schrock and Matthew Conley from the University of California, Riverside have developed new W and Mo based alkylidene olefin metathesis catalysts that can be produced by activation of metathesis-inactive precursors, accessible from metal chloride precursors via as few as three synthetic steps, using visible light. 𝛃,𝛃'disubstituted tungsten cyclopentane complexes can be prepared in the dark and form alkylidenes through irradiation. This technology is advantageous because it can potentially regenerate used catalysts by irradiation with visible light, offering a sustainable and cost-effective approach for industrial and research applications.
Suggested uses
- A potential sustainable and cost-effective approach for the production Mo-/W-based metathesis catalysts for industrial and research applications.
- For use in various industries including agrochemical, renewables, pharmaceutical, flavors and fragrances, polymers, and advanced materials.
