Electric Literature of 108-47-4, 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, 108-47-4, 2,4-Dimethylpyridine, introducing its new discovery.
Catalytic C-H bond addition of pyridines to allenes by a rare-earth catalyst
The catalytic C-H addition of pyridines to allenes has been achieved for the first time by using a half-sandwich scandium catalyst, thus constituting a straightforward and atom-economical route for the synthesis of alkenylated pyridine derivatives. The reaction proceeded regio- and stereoselectively, affording a new family of alkenylated pyridine compounds which are otherwise difficult to synthesize. A cationic Sc-eta2-pyridyl species was isolated and confirmed to be a key catalyst species in this transformation.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 108-47-4. In my other articles, you can also check out more blogs about 108-47-4
