Robust heterometallic MOF catalysts for the cyanosilylation of aldehydes

In this work, Zn2+ and Cu2+ ions are doped into a Mn2+ based frail MOF (STU-2) to form heterometallic MOFs. These metal doped MOFs show a good stability and heterogeneous catalytic activity for the cyanosilylation reactions of aromatic aldehydes. The catalysts can be reused at least for three cycles.
