Conformational preference and configurational control of highly symmetric spirobi[dibenzazepinium] cation.
[formula: see text] Stereodynamics were detected in solution for salts of the simple spirobi[dibenzazepinium] cation in favor of the homochiral (D2) conformer as evidenced by chiral TRISPHAT and BINPHAT counterions; asymmetric induction was furthermore observed in 1H and 15N NMR spectroscopy.
