Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 138530-94-6, Name is (R)-Lansoprazole, molecular formula is , belongs to indole-building-block compound.

Chitosan Cu-Catalyzed C3-Sulfenylation of Indoles with Sulfur Powder and Aryl Iodides
Aiming at the problem that the catalyst can not be recovered during the construction of the C-S bond in the indole ring with sulfur powder as the sulfur source, 2-pyridinecarboxylic acid modified chitosan (PACS) catalyst with different type of copper was prepared, which was used to catalyze the three-component reaction of indole, sulfur powder and iodobenzene to prepare C-3 thioether-based indole in a one-pot method. The reaction yield is as high as 92%, and the substrate has good applicability. The most suitable catalyst [PACS(d;Cu(OAc)(2)] was characterized and analyzed by thermogravimetric analysis (TGA), scanning electron microscope(SEM), X-ray photoelectron spectroscopy(XPS), etc. It shows that the catalyst has the advantages of no additional ligand, easy separation and reusable.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 138530-94-6, in my other articles.
