Abstract

The functionalization of diazines is of great importance, because these N-heterocycles are present in numerous natural products, pharmaceuticals, and agrochemicals.[1] They also find applications in materials science and polymer chemistry.[2] The directed metalation and further functionalization of these electron-deficient N-heterocycles can be realized with ate bases [3] and in some cases with lithium bases.[4] However, low temperature and ...
