摘要：A new family of imidazole-coordinated monodentate NHC-metal complexes 9 was obtained as well as cis-chelated bidentate NHC-metal complexes 10 from novel bis(imidazolium) salts 4 with a biphenyl backbone. The structures of complexes 9a and 10b were determined by X-ray crystal-structure diffraction, and their application in the Heck reaction showed good to excellent catalytic activities under very mild conditions.
