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.
从商业的氯二嗪开始,我们报道了吡啶-2-基二嗪的合成。报道了这些化合物的第一次锂化和官能化,并讨论了金属化的区域选择性。通过金属化反应进行的功能化提供了取代的吡啶-2-基二嗪的新途径,其可以用作超分子的组成部分。
