The first tricyclic [12]annulene with an unsubstituted perimeter, namely the blue hydrocarbon 2, could be prepared from the azulene derivative 1. Compound 2 proved to be an antiaromatic 12π-electron system par excellence
Cycloadditions to the azulene system have not hitherto been observed. Instead, azulene reacts, e.g.,...
