    • All of the four olefinic protons in endo-dicyclopentadiene (dcp) are nonequivalent, hence, a separate signal for each proton should be observed. However, chemical shifts of Ha and Hb are very close to each other and they are observed as one broad mutiplet around 5.48 ppm. For the same reason, Hc and Hd are also observed as one broad multiplet around 5.95 ppm. In the, dcp)RhCl]2 (3, both H c and Hd Figure presented ando-Dicyclopentadiene are upfield shifted to the same extent and are observed as one signal around 4.66 ppm. However, geometric arrangement of Ha is quite different from Hb in Rh complex 3, which gives rise to upfield shift of one proton (Ha or Hb) and downfield shift of other Ha or Hb, For more details, see ref 15
