Amine for it! A cationic rhodium catalyst, which was assembled in situ from commercial components, promoted the reaction of a range of simple 2‐aminobenzaldehydes with terminal and internal alkynes in a series of intermolecular hydroacylation reactions. The products of this reaction, amino‐substituted enones, were efficiently converted into the corresponding dihydro‐4‐quinolones.

We demonstrate that a single Rh(i) complex can promote two mechanistically distinct C–C bond-forming reactions – alkyne hydroacylation and aryl boronic acid conjugate addition – to deliver substituted ketone products from the controlled assembly of three readily available fragments.
