Abstract
Although the paper published by Kekule in 1865 is generally accepted as the seminal document regarding the elucidation of the structure of benzene, it was not for another seven years that Kekule introduced a "collision theory" which, in his view, made the 1,3,5-cyclohexatriene formulation at last acceptable. 2022 is therefore an appropriate year to celebrate the 150(th) anniversary of his proposal. The present Perspective focusses in particular on how Kekule's mind has evolved during that short period of time. After a short introduction, followed by a historical note about the emergence of aromatic chemistry and the role of Kekule as founder of structural organic chemistry, this Perspective discloses in three chapters the step-by-step unveiling of the 1,3,5-cyclohexatriene structure and focusses on Kekule's own dubiety about this formula. Eventually, in 1872 Kekule's benzene saga is completed in the article in which he discloses his final theory on the structure of benzene. In the last section, a short review is presented on the later quest for a fully symmetric single-formula representation of benzene.
