Description

Application

It′s a phosphine free version of Grubbs 2^nd Generation Catalyst with comparable reactivity, but initiates more readily at lower temperatures. Efficient for metathesis of electron-deficient substrates including fluorinated olefins. Demonstrated in multiple large-scale pharmaceutical applications.
It can be used as a catalyst for olefin cross-metathesis with fluorinated olefins (CM), ring-closing metathesis (RCM), ring-opening metathesis (ROM), and a sequence of a metathesis reaction and subsequent dihydroxylation of the newly formed double bond.
