Nonproductive Events in Ring-Closing Metathesis Using Ruthenium Catalysts [PDF]
, 2010 The relative TONs of productive and nonproductive metathesis reactions of diethyl diallylmalonate are compared for eight different ruthenium-based catalysts. Nonproductive cross metathesis is proposed to involve a chain-carrying ruthenium methylidene.
