A general approach for the synthesis of bis(imidazolium) dichloride salts from imidazoles and dichloroalkanes is reported. Typical limitations of this reaction for the formation of methylene-bridged derivatives are addressed herein through the use of excess CH2Cl2 in the presence of DMSO as a polar cosolvent, significantly improving the conversion rates presumably via stabilization of the initial SN2 transition state. The method also is applicable to the formation of bis(pyridinium) dichloride salts from pyridine derivatives, and to the direct synthesis of metal-bis(NHC) complexes from imidazoles.
