Özet

A series of new RhI–N-Heterocyclic carbene dinuclear complexes of type [Rh(µ-Cl)(η2-coe)(NHC)]2, containing IPrBIAN, IPrCl, and IPr* ligands, has been prepared. The crystal structure of the IPrCl functionalized rhodium–dinuclear complex reveals an intermolecular Cl···Cl halogen bond. The chlorido-bridges can be cleaved by pyridine to afford the corresponding mononuclear derivatives RhCl(η2-coe)(NHC)(py). These complexes are efficient alkyne hydropyridonation catalysts, with the IMes complex exhibiting the highest reactivity within the series.
