Abstract
An efficient two-step method was developed for the synthesis of 1,2-di(azulen-1-yl)ethenes 15–17, having the double bond included in a five-membered carbocyclic or heterocyclic ring. The method involves preparation of the appropriate diketone precursors through Vilsmeier–Haack or Friedel–Crafts reactions, followed by their McMurry cyclization. Alkenes 16 and 17 were quantitatively converted into the corresponding dehydro derivatives 24 and 25, respectively, by oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). The electrochemical properties of compounds 15–17, 24 and 25 were examined by cyclic voltammetry (CV) and differential pulse voltammetry (DPV), and the relationship between their structure and electrochemical behavior was established.
