Möbius Antiaromatic Bisphosphorus Complexes of [30]Hexaphyrins

Möbius Antiaromatic Bisphosphorus Complexes of [30]Hexaphyrins

Aromaticity with a twist: The reversal of Möbius aromaticity occurs by changing the number of π electrons between [4n+2] and [4n] in monophosphorus complexes of [28]hexaphyrins and bisphosphorus complexes of [30]hexaphyrins. The 30π Möbius antiaromatic bisphosporus[30]hexaphyrins (see picture) were...

Zusammenfassung:Aromaticity with a twist: The reversal of Möbius aromaticity occurs by changing the number of π electrons between [4n+2] and [4n] in monophosphorus complexes of [28]hexaphyrins and bisphosphorus complexes of [30]hexaphyrins. The 30π Möbius antiaromatic bisphosporus[30]hexaphyrins (see picture) were determined to be the first structurally characterized Möbius antiaromatic systems, which are rigid, neutral, and stable.
