nitro-Grela-I₂ SIPr

nitro-Grela-I₂ SIPr

Chemical name:


Product number: AS2053

CAS number: 1874265-00-5

Patent number: PCT/EP2003/011222

Ask for availability



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.
