Grubbs catalyst 2nd generation synthesis

2synthesis methods
Grubbs and co-workers reported a direct approach towards the preparation of the 4,5-dihydroimidazol-2-ylidene-substituted ruthenium-based catalysts. Compared to their predecessor, Grubbs catalyst 2nd generation display higher reactivity, better stability, and improved functional group tolerance.[3]
