Application

nitro-Grela is a universal catalyst which provides good results in a wide spectrum of olefin metathesis transformations. The catalyst provides high efficiency in cross metathesis (CM) reactions between type 1 olefins and an electron deficient partner. The catalyst is very good for CM of disubstituted internal olefins.
