    • note
    • NICS is defined as the negative of the absolute magnetic shieldings computed, for example, at the unweighted geometric center of aromatic or antiaromatic rings [NICS(0)] or 1 Å above the ring [NICS(1)]. Significantly negative NICS values indicate the presence of diatropic ring current and, therefore, aromaticity in the systems.

    • Although the classical 1,2-dilithiocyclopropene is a stationary point at HF/STO-3G (Jemmis, E. D.; Chandrasekhar, J.; Schleyer, P. v. R. J. Am. Chem. Soc. 1979, 101, 2848), the dibridged isomer (26) is 16.3 kcal/ mol more stable. However, the classical structure collapses to 26 at higher levels of theory (for example, HF/3-21G and B3LYP/6-311+G*).
