Refluxing2a-cwith nickelocene in THF yielded the neutral cyclopentadienyl NHC nickel(II) complexes3a-c. Their structures were defined by NMR, IR and elemental analysis techniques. Molecular weights of3a-cwere affirmed by MALDI-TOF mass spectrometry. Catalytic tests of3a-cwere performed in Kumada coupling of some aryl chlorides with phenylmagnesium bromide at 25 degrees C.
