Synthetic Route of 3622-40-0. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 3622-40-0, Name is 2-Bromo-4-chlorobenzo[d]thiazole. In a document type is Article, introducing its new discovery.
A one-pot universal approach for transforming arylamines to aryl halides via reaction with sodium nitrite (NaNO2) and N-halosuccinimide (NXS) in DMF at room temperature under metal- and acid-free condition is described. This new protocol that is complementary to the Sandmeyer reaction, is suggested to involve the in situ generation of nitryl halide induce nitrosylation of aryl amine to form the diazo intermediate which is halogenated to furnish the aryl halide.
