Kekulé's proposal for the structure of benzene (1872).

Summary

[edit]
Description
Deutsch: August Kekulés Vorschlag für die Benzol-Strukturformel im Original, entnommen aus:
English: August Kekulé's proposal for the benzene structure in its original, taken from:
August Kekulé (1872). "Ueber einige Condensationsproducte des Aldehyds". Liebigs Ann. Chem. 162 (1): 77–124. DOI:10.1002/jlac.18721620110. "[…] man sieht daher, dass jedes Kohlenstoffatom mit den beiden anderen, mit welchen es zusammenstösst, gleich oft zusammenprallt, also zu seinen beiden Nachbarn genau in derselben Beziehung steht. Die gewöhnliche Benzolformel drückt natürlich nur die in Einer Zeiteinheit erfolgenden Stösse […] aus, und so ist man zu der Ansicht verleitet worden, Biderivate mit den Stellungen 1,2 und 1,6 müssten nothwendig verschieden sein. Wenn die eben mitgetheilte Vorstellung oder eine ihr ähnliche für richtig gehalten werden darf, so folgt daraus, dass diese Verschiedenheit nur eine scheinbare, aber keine wirkliche ist."
