Molecular
squares obtained from two olefin-bridged bis(NHC) ligands,
NHC–Ar–CC–Ar–NHC, and two Ag+ or Au+ ions undergo postsynthetic modifications
via a UV-irradiation-initiated [2 + 2] cycloaddition reaction to yield
the corresponding cyclobutane-bridged dinuclear tetrakis(NHC) complexes.
The tetrakis(NHC) ligand can be liberated from the AgI complexes
as the tetraimidazolium salt. For the AuI complexes, the
substituents at N3 and N3′ of the dicarbene ligands determine
the outcome of the reaction in the solid state.
