In this paper, copper(i) amidate complexes (), proposed intermediates in copper-catalyzed Goldberg reaction, have been prepared and characterized by elemental analysis, IR, (1)H NMR and X-ray crystallography. Ancillary ligand bis(diphenylphosphino)ferrocene (dppf) has contributed greatly to the stability of the copper-amidate complexes due to its strong chelating ability and weak intermolecular interactions. Thermal gravimetric analyses are carried out to determine the thermal competency of complexes as the intermediates of the high-temperature Goldberg reactions. Reaction of complexes and with aryl halides generates the N-arylation products , accompanied by the formation of a copper(i) complex Cu(dppf)X (X = I or Br) , which has been determined by LC-MS analysis. These results provide new evidence for the mechanism of copper(i)-catalyzed Goldberg reaction. |
