Application

Metathesis: Ruthenium-Based Metathesis Catalysts

Catalyst for ring-closing metathesis, cross metathesis and ROMP able to produce trisubstituted olefins via cross metathesis, and ring closes olefins with excellent functional group tolerance and selectivity.

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.

Enyne Metathesis

Enyne metathesis has emerged as a powerful method for the synthesis of conjugated dienes.1 Botta and coworkers utilized a similar approach, where the olefin was replaced with an enol ether. Reaction ...
