The aromaticity and Möbius characteristics of carbeno[8]heteroannulenes and triplet state annulenes.
نویسندگان
چکیده
Two types of annulene which may show significant Möbius aromatic character and bond and twist delocalisation are proposed; triplet states with 4n + 2 occupancy of the p pi array of atomic orbitals and a novel 8-pi carbeno[8]heteroannulene ring system 1 where the Hückel highly antiaromatic nature as a planar system can be attenuated or even reversed by the C2 symmetric Möbius distortion.

Aromaticity is a property usually linked to the ground state of stable molecules. Although it is well-known that certain excited states are unquestionably aromatic, the aromaticity of excited states remains rather unexplored. To move one step forward in the comprehension of aromaticity in excited states, in this work we analyze the electron delocalization and aromaticity of a series of low-lyin...

Three major approaches have been developed to predict outcomes for concerted reactions controlled by orbital symmetry analysis using (i) correlation diagrams1, (ii) frontier orbital interactions in transition states2 and (iii) incipient aromatic/ antiaromatic character in transition states3-5. The latter approach (Zimmerman-Dewar or Hückel-Möbius) is particularly simple to teach to undergraduat...

متن کاملMöbius Aromaticity : Which Side Are You on ?
INTRODUCTION The idea of Möbius aromaticity was first proposed by Heilbronner in 1964. He postulated that a molecule could gain Möbius aromatic stabilization if the nuclear framework were twisted so the porbitals composing the π-system would contain an odd number of nodes. To introduce a node in the orbitals, Heilbronner theorized that a series of p-orbitals could itself be twisted by contortin...
