Hydroxide-Induced Degradation of Olefin Metathesis Catalysts: A Challenge for Metathesis in Alkaline Media
Sign Up to like & getrecommendations! Published in 2020 at "ACS Catalysis"
DOI: 10.1021/acscatal.9b05163
Abstract: Hydroxide ion is shown to be a potent disruptor of Ru-catalyzed olefin metathesis, in a study of the Hoveyda catalyst HII. Addition of [NnBu4][OH] immediately terminates metathesis via HII, an effe... read more here.
