Doubled up : A rhodium(III)/copper(II) system co‐catalyzes the annulation of benzimides with internal alkynes for the synthesis of indenones (see scheme; Cp*=C 5 Me 5 ). The reaction involves an uncommon nucleophilic addition of a transition‐metal–carbon bond to an imide moiety. This novel reaction provides a facile route to synthesize indenones from readily available benzimides and internal alkynes.
