Abstract

In contrast to the 1,6-X-[10]annulenes (X = CH2, O, NH) with delocalized forms (c), their X = PH and S counterparts favor the bisnorcaradiene structures (b). Forms b and c are close in energy with X = SiH2 and Web The computed nucleus independent chemical shifts (NICS), show both annuienes (c) and cyclic polyenes (a) to be aromatic. Strain-introduced structural localization, e.g., due to four bulky SiMe3 substituents, reduces but does not eliminate aromaticity.
