    • 1H NOESY spectra was taken with a mixing time of 600 msec. Cross peaks were observed between vinyl proton and α-protons of the ferrocenyl substituent, but not between ethyl protons and thienyl protons, and between vinyl proton and ethyl protons. (In comparison, we were able to observe cross peaks between the vinyl proton and ethyl protons of 12)
