✦ Synopsis
Conformational analysis / Benzene, donor-acceptor-substituted / Benzene ring, distortion of J Cyanine concept
The rc system of la may adopt markedly different electronic structures with concomitant strong conformational preferences for the six-membered ring. Neutral la can exist either in a quinoid boat form or as a twist boat, formally resulting
