Abstract Whether tetra‐tert‐butyl‐s‐indacene is a symmetricD2hstructure or a bond‐alternatingC2hstructure remains a standing puzzle. Close agreement between experimental and computed proton chemical shifts based on minima structures optimized at the M06‐2X, ωB97X‐D, and M11 levels confirm a bond‐localizedC2hsymmetry, which is consistent with the expected strong antiaromaticity of TtB‐s‐indacene.more » « less
