Durch KondensationvonVerbindungen mit reaktionsfähiger Methyl- oder Methylengruppe mit den Vinylenhomologen desBenzaldehyds bis zum ω-Phenylhendekapentaenal werden unsymmetrische Phenylmethine aufgebaut. Es wird der Verlauf der Vinylensprünge in grossen Zügen erfasst und auf einige Problemstellungen hingewiesen.

11-Anisyl-hendekapentaenal wird synthetisiert und für p-Methoxyzimtaldehyd eine verbesserte Methode angegeben. Es werden verschiedene unsymmetrische Anisylmethine beschrieben. Der Vergleich mit den analogen Phenylmethinen zeigt, dass mit wachsender Vinylenkette der bathochrome Einfluss der Methoxylgruppe abnimmt.
