Application:	Grubbs Catalyst^® M204 can be used as a catalyst for ring-closing metathesis (RCM), cross-metathesis, and ring-opening metathesis polymerization (ROMP). It is also used to synthesize trisubstituted olefins with excellent functional group tolerance and selectivity via cross-metathesis and ring closing metathesis reactions. It can also be used as a catalyst: • To synthesize coumarins from phenolic compounds via RCM. • To cleave secondary (E)-allyl vic-diols to aldehydes. For small scale and high throughput uses, product is also available as ChemBeads (919764 ) Learn more about our metathesis catalysts
