New Insights into the Mechanism of Ruthenium-Catalyzed Olefin Metathesis Reactions
TL;DR: A detailed mechanistic study of phosphine exchange and initiation kinetics in alkylidenes 1 and 2 is reported, providing new and surprising evidence concerning the origin of the large activity differences between these two catalysts.
Journal ArticleDOI
Ruthenium Carbene-Based Olefin Metathesis Initiators: Catalyst Decomposition and Longevity
Michael Ulman,Robert H. Grubbs +1 more
TL;DR: In this article, the authors studied thermolytic decomposition pathways for several ruthenium carbene-based olefin metathesis catalysts and compared the longevity of these catalysts.
Journal ArticleDOI
Relative Reaction Rates of Olefin Substrates with Ruthenium(II) Carbene Metathesis Initiators1
Michael Ulman,Robert H. Grubbs +1 more
TL;DR: The metathesis of terminal olefins having different steric bulk and different geometries as well as electronically different para-substituted styrenes was studied with the ruthenium-based metathesi....
Journal ArticleDOI
A series of ruthenium(II) ester-carbene complexes as olefin metathesis initiators: metathesis of acrylates
TL;DR: In this paper, a series of ester-carbene complexes were synthesized for the metathesis of olefinic substrates, including acrylates and trisubstituted olefins.
