nitro-Grela-I2 SIPr

Chemical name:

(1,3-bis(2,6-diisopropylphenyl)imidazolidin-2-ylidene)diiodo(2-isopropoxy-5-nitrobenzylidene)ruthenium(II)

Product number:

AS2053

CAS number:

1874265-00-5

Patent number:

PCT/EP2003/011222

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.
