Overview

Metathesis: Ruthenium-Based Metathesis Catalysts Metathesis catalyst with efficiencies similar to Grubbs Catalyst 2nd generation but with different substrate specificity. Catalyzes ring-closing, ring-opening, and cross-metathesis reactions of highly electron-deficient substrates. Hoveyda-Grubbs 2nd Generation Catalyst &bull Phosphine free version of Grubbs 2nd Generation Catalyst with comparable reactivity, but initiates more readily at lower temperatures. &bull Efficient for metathesis of electron deficient substrates. &bull Catalyst for olefin cross metathesis with fluorinated olefins(CM) &bull Catalyst for ring closing metathesis(RCM)
