Azulene 1, pentalene 2, and heptalene 3 are classical nonalternant hydrocarbons. Their fascinating π-frameworks, consecutive arrangements of odd-membered carbocycles, have engaged chemists’ attenti...

Aryl acetylenes bearing electron-withdrawing groups have been found that can add to azulenes and yield 1,2-substituted heptalenes. Theoretical studies of the reaction mechanism helped to design the candidate molecules that have then been tested in th

Polycyclic conjugated non-benzenoid hydrocarbons are of great theoretical interest in connection with the question of the relationships between structure and aromaticity[1].

A nonbenzenoid hydrocarbon, difluoreno[1,9,8- alkj:1',9',8'- gfed]heptalene 1, is synthesized. Experimental and theoretical investigations demonstrate that the planar and symmetric heptalene core within 1 effectively induces the antiaromatic and open

Heptalene has a fused structure of two cycloheptatrienes which is one of the non-aromatic bicyclic molecules with a 12π-electronic structure. We report herein the synthesis of thiophene-fused heptalene derivatives from the corresponding azulenothiop

The stereochemical reactivities of monocyclic unsaturated compounds having 3–5 and 7–8 membered rings and of bicyclic pentalenes and heptalene can be rationalized through the bent bond/antiperiplanar hypothesis (BBAH) orbital model at the molecul
