Шаблон:Short description Шаблон:Chembox
Benzotriyne or cyclo[6]carbon is a hypothetical compound, an allotrope of carbon with molecular formula Шаблон:Chem2. The molecule is a ring of six carbon atoms, connected by alternating triple and single bonds.[1] It is, therefore, a potential member of the cyclo[n]carbon family.
There have been a few attempts to synthesize benzotriyne, e.g. by pyrolysis of mellitic anhydride,[2] but without success Шаблон:As of. Calculations suggest that the alternative cyclic cumulene structure, called cyclohexahexaene, is the potential energy minimum of the cyclo[6]carbon framework. It is unclear whether this second structure is an isomer or a limiting resonance structure.[3]
