The first circular dichroism observation for organic radical cations: chiroptical properties of neomenthyloxy- and isobornyloxyanisole radical cations.
The first unequivocal circular dichroism spectra were obtained for organic radical cations, which were prepared from p-(1S,2S,5R)-neomenthyloxyanisole (1) and p-(1S,2S,4S)-isobornyloxyanisole (2) by single electron oxidation with triethyloxonium hexachloroantimonate in dichloromethane. The chiroptical properties of the radical cations 1*+ and 2*+ were discussed in comparison with those of neutral species 1 and 2.
