As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 108-47-4, Name is 2,4-Dimethylpyridine, belongs to chiral-nitrogen-ligands compound, is a common compound. 108-47-4Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In an article, authors is Alvarez, once mentioned the new application about 108-47-4.
A series of thieno[2,3-f]-, [3,2-f]- and [3,4-f]morphans prepared both by the Grewe synthesis and by the reaction of 2-cyanopyridines with 3-thienyllithium is described. Furthermore, a new synthetic route to thieno[2,3-f]morphans from 3-ketotetrahydrothiophene is reported. Separation and assignment of the alpha- and beta-diastereomeric structures by means of nmr data is reported. Some side products were isolated and their structures were confirmed on the basis of their spectral data. Mechanisms for their formation are proposed.
Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. In my other articles, you can also check out more blogs about 108-47-4. 108-47-4
