A carbene-catalyzed oxidative cycloaddition reaction is developed for efficient access to multi-functionalized 2-phenylbenzothiazoles. A broad scope of heavily substituted arenes bearing 2-benzothiazole groups were prepared in good to excellent yields. The remote C(sp2)-H bond in the substituted arene products can be activated by Pd catalysts in regio-selective fashion with the direction of the 2-benzothiazole groups. In the experiment, the researchers used many compounds, for example, 1,3-Dimesityl-1H-imidazol-3-ium chloride(cas: 141556-45-8Quality Control of 1,3-Dimesityl-1H-imidazol-3-ium chloride)
1,3-Dimesityl-1H-imidazol-3-ium chloride(cas: 141556-45-8) is a ligand for arylation of aldehydes and for carbene catalyzed intermolecular arylation of C-H bonds. It is used as a phosphine-free ligand in various metal-catalyzed coupling reactions, often with advantageous results in difficult cases.Quality Control of 1,3-Dimesityl-1H-imidazol-3-ium chloride
