Description
Very good for mRCM (macrocyclization) and small/medium ring formation from sterically non-demanding substrates. Very good for CM of terminal, type 1 olefins. Good for CM with substrates bearing unprotected alcohols. Less sensitive to impurities than nitro-Grela and nitro-Grela-SIPr. Suppressed formation of non-metathetic byproducts.
