Fig. 7. Cyclic voltammograms of 3aa, 4aa, and syn- and anti-5ah. (a) 3aa and 4aa in CH₃CN. (b) syn- and anti-5ah in CH₂Cl₂. n-Bu₄NPF₆ (0.1 M) was chosen as the supporting electrolyte, and Ag/AgCl was chosen as the reference electrolyte. The ferrocene/ferrocenium ion couple was employed as an external reference. Scan rate: 50 mV s^–1.
