Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Angewandte Chemie, International Edition called Nickel-Catalyzed Inter- and Intramolecular Aryl Thioether Metathesis by Reversible Arylation, Author is Delcaillau, Tristan; Bismuto, Alessandro; Lian, Zhong; Morandi, Bill, which mentions a compound: 17696-11-6, SMILESS is O=C(O)CCCCCCCBr, Molecular C8H15BrO2, Recommanded Product: 17696-11-6.
A nickel-catalyzed aryl thioether metathesis was developed to access high-value thioethers. 1,2-Bis(dicyclohexylphosphino)ethane (dcype) is essential to promote this highly functional-group-tolerant reaction. Furthermore, synthetically challenging macrocycles could be obtained in good yield in an unusual example of ring-closing metathesis that does not involve alkene bonds. In-depth organometallic studies support a reversible Ni0/NiII pathway to product formation. Overall, this work not only provides a more sustainable alternative to previous catalytic systems based on Pd, but also presents new applications and mechanistic information that are highly relevant to the further development and application of unusual single-bond metathesis reactions.
As far as I know, this compound(17696-11-6)Recommanded Product: 17696-11-6 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
