Starting from commercial chlorodiazines, we report the synthesis of pyridin-2-yldiazines. The first lithiation and functionalization of these compounds are reported and the regioselectivity of the metallation is discussed. The functionalization via the metallation reaction, provides a new access to substituted pyridin-2-yldiazines, which could be used as building blocks in supramolecules.
