Preparation of Conjugated Polyenes with Anthryl and N-Methylpyridinium Terminal Groups The synthesis of terminally donor-acceptor substituted polyenes from the respective aldehydes via Horner reactions is described. As donor group the 9-anthryl and as acceptor moiety the 4-(N-methyl)pyridinium residue were chosen. A bicyclo[2.2.2]octane unit was incorporated into the chain to interrupt the conjugation. The separation and characterization of the mixtures of Z/E- isomers obtained in the syntheses was possible.
