N2  - The methyl substituents of diquaternized 4,4&#8242;&#8722;dimethyl-2,2&#8242;-bipyridine are suff iciently acidic to be used as the source of a bridgehead carbon in the formation of cage amine derivatives from &#91;Co(sen)&#93;3+ &#91;sen = 4,4&#8242;,4&#8242;&#8242;-ethylidynetris(3-azabutan-1-amine)&#93;. The resulting octapositive bis(cage)-bipyridinium species can be obtained in both meso and optically active forms, the latter showing readily detectable potential shifts in the presence of enantiomeric anions.
