Abstract

Abstract Bisquinones 16–20, in which the quinoid moieties are tethered by 2-6 methylene units, have been synthesized via the bis (dimethoxybenzenes) 2, 6, 9, 14, and 15. Compounds 16–20 were transformed into the corresponding bis (DCNQIs) 21–25 using standard procedures. Interactions between the two quinoid units, which fade with the length of the tethering chain, have been observed by 13 C-NMR spectroscopy, backed by ...
