Challenging Metathesis Catalysts with Nucleophiles and Brønsted Base: Examining the Stability of State-of-the-Art Ruthenium Carbene Catalysts to Attack by Amines
(Journal article; Peer reviewed, 2020)Critical to advancing the uptake of olefin metathesis in leadingcontexts, including pharmaceutical manufacturing, is identification of highlyactive catalysts that resist decomposition. Amines constitute an aggressivechallenge ... -
Ethylene-Triggered Formation of Ruthenium Alkylidene from Decomposed Catalyst
(Journal article; Peer reviewed, 2020)Ethylene is known to readily decompose ruthenium-based olefin metathesis catalysts, such as Grubbs second-generation catalyst (GII), by forming the unsubstituted ruthenacyclobutane (Ru-2) that may undergo a 1,2-H shift and ... -
The Impact of Water on Ru-Catalyzed Olefin Metathesis: Potent Deactivating Effects Even at Low Water Concentrations
(Journal article; Peer reviewed, 2021)Ruthenium catalysts for olefin metathesis are widely viewed as water-tolerant. Evidence is presented, however, that even low concentrations of water cause catalyst decomposition, severely degrading yields. Of 11 catalysts ...
