A Mild and Direct Site-Selective sp2 C-H Silylation of (Poly)Azines.

A base-mediated protocol that allows for the site-selective sp2 C-H silylation of azines is described. This method is distinguished by its mild conditions, simplicity and excellent site-selective modulation for a diverse set of azines, even in the context of late-stage functionalization, while exhibiting orthogonal reactivity with classical silylation reactions.
