摘要: The η5-cyclopentadienylpentadienylnickel complexes 5 and 6 contain η3-1-vinylallyl groups. There is no evidence of coordination the vinylic CC bond to nickel in either syn or anti isomers 6a 6b. 1H NMR saturation transfer experiments indicate that 6b exists an equilibrium between two valence isomers.
