Abstract

Abstract Cleavage of a C [BOND] N bond of imidazolium salt derived from N-phenyl- substituted proline was observed in this laboratory. A novel imidazole-coordinated monodentate NHC–Pd (II) complex 5 was obtained as the sole product in good yield in the reaction of imidazolium salt 4 with Pd (OAc) 2 in refluxing THF. The structure of complex 5 was determined unambiguously by an X-ray diffraction. The complex was found to be a ...
