摘要：

The reaction of a pentadentate NHC ligand precursor with Ni(OAc)(2)<bold></bold>4H(2)O or Pd(OAc)(2) in the presence of a base yields four-coordinate square-planar Ni(ii) and Pd(ii) complexes with an unusual ligand generated in situ. A series of experimental studies point to a ring-opening and ring-closing process via novel C-N bond cleavage and formation.
