Description

Excellent for CM of terminal, type 1 olefins. Provides improved selectivity in metathesis of substrate bearing unprotected -OH and -COOH groups. Very good for RCM with sterically non-demanding substrates leading to small/medium rings. Less sensitive to small impurities than nitro-Grela and nitro-Grela-SIPr catalysts.
