On October 2, 2020, Stentzel, Michael R.; Klumpp, Douglas A. published an article.SDS of cas: 14602-86-9 The title of the article was Michael Addition with an Olefinic Pyridine: Organometallic Nucleophiles and Carbon Electrophiles. And the article contained the following:
The conjugate addition reactions of trans-1,2-di(2-pyridyl)ethylene have been studied. This substrate reacts with organolithium nucleophiles, and the resulting anionic intermediates may be trapped by proton or various carbonyl-based electrophiles. It is suggested that the dipyridyl structure stabilizes the intermediate carbanion, allowing the Michael adduct to be captured by an added electrophile. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).SDS of cas: 14602-86-9
