Application of 14871-92-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 14871-92-2, (2,2′-Bipyridine)dichloropalladium(II), introducing its new discovery.
Oxidative addition of donor-functionalised 4-iodoimidazolium salts to palladium(0) provides a selective route for the preparation of abnormal chelating N-heterocyclic carbene complexes and enables the introduction of a variety of donor groups. The activation of the C4 position does not necessitate protection of the imidazolium C2 position, thereby leaving this site available for further modification. While metallation of the unsubstituted C2 position of the N-heterocyclic carbene ligand was unsuccessful when palladium was bound to the C4 carbon atom, sequential metallation of first the C2 position, by means of transmetallation, followed by C4-I oxidative addition, afforded a dimetallic complex comprised of two palladium centres bridged by a single NHC ligand. Oxidative addition of 4-iodoimidazolium salts to low-valent palladium(0) provides access to abnormal NHC-palladium complexes without requiring protection of the C2 position. Hence, this site is available for further functionalisation which allows, for example, dimetallic complexes to be prepared.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 14871-92-2. In my other articles, you can also check out more blogs about 14871-92-2
