Excellent 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. Suitable for reaction in green solvents without degassing and drying.
