Reactivation of a ruthenium-based olefin metathesis catalyst

Article abstract of DOI:10.1021/om301042a

First-generation Hoveyda-Grubbs olefin metathesis catalyst was purposely decomposed in the presence of ethylene, yielding inorganic species that are inactive in the ring-closing metathesis (RCM) of the benchmark substrate diethyl diallylmalonate (DEDAM).
