产品介绍	Grubbs第二代催化剂和第一代催化剂相比更有活性，且具有更广泛的底物范围，包括对空间有要求或失活的烯烃，如1,1 - 二取代烯烃和α，β-不饱和羰基化合物 Grubbs 2nd Generation Catalyst Generally more active compared to 1st generation catalysts and with a broader substrate scope, including sterically demanding or deactivated olefins such as 1,1-disubstituted olefins and α,β-unsaturated carbonyls 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.
