Abstract

The ground-state rotamer conformations of a series of'bisected'dicyclopropylcarbinyl cations, cyclopropylallyl cations, and phenylcyclopropylcarbinyl cations have been systematically investigated for the first time, employing 1H and 13C nmr spectroscopy. In the absence of significant steric factors, these cations adopt conformations involving the'most extended conjugation.'However, this preference is not overwhelming because, in the presence of ...
