Chemical name:


Product number: AS2034

CAS number: 1448663-06-6

Patent number: PCT/EP2013/062435

Ask for availability



General purpose catalyst, very good for CM of internal, 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. Suitable for reaction in green solvents without degassing and drying.

Similar properties to CoolCat, reaction results may vary depending on conditions or different substrate
