Chemical name:


Product number: AS2033

CAS number: 928795-51-1

Patent number: PCT/EP2003/011222

Ask for availability



General purpose catalyst, very good for CM of terminal and disubstituted trans olefins of type 1. Very good for RCM with sterically non-demanding substrates leading to small/medium rings and for CM with electron deficient partners such as acrylates. Less sensitive to small impurities than nitro-Grela catalyst.
