文摘

A series of Hoveyda-Grubbs benzylidenes, Ru(X)₂(IMesH₂)(=CH-2-(2-PrO)C₆H₄) (X = Cl, Br, CF₃CO₂, C₂F₅CO₂; IMesH₂ = 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene)were demonstrated to undergo intermolecular anionic ligandexchange when mixed. The implication is that anionic ligandexchange is occurring between identical ruthenium benzylidenesat all times in solution. A mechanism involving bridged dimersis invoked.
