We have developed a C2-selective dehydrogenative mono-silylation of a variety of pyridines using a Rh-Al complex [(R2PCH2N-1,2-C6H4NMe-1,2-C6H4NCH2PR2)AlClRhCl(L)]n (R = Ph, iPr; n = 1, L = nbd; n = 2, L void). Both the site- and mono-selectivity are controlled via the pyridine coordination to the Lewis-acidic Al center prior to the activation of the pyridine C(2)-H bond at the proximal Rh center. A reaction mechanism is proposed based on several mechanistic studies, including the isolation of a (2-pyridyl)silylrhodium intermediate.
