Organic selenides were efficient regioselective synthesized by palladium-catalyzed switchable mono- and diselenylation of arenes sp2 C-H bonds through simply tuning the DMSO to water ratio. The present protocol was also successfully extended to the monoselenylation of 2-phenoxypyridines, which bore a removable directing group, in modest yields. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0SDS of cas: 4783-68-0).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.SDS of cas: 4783-68-0
