Abstract

The preparation of three series of [(NHC) CuX] complexes (NHC= N-heterocyclic carbene, X= Cl, Br, or I) is reported. These syntheses are high yielding and only use readily available starting materials. The prepared complexes were spectroscopically and structurally characterized. Notably, two of them present a bridging NHC ligand between two copper centers in the solid state, an extremely rare coordination mode for these ligands. These ...
