How the Orientation of BN Units Influences the Aromaticity of Some Iminobora-Benzenes
Fecha de publicación: 07/02/2025

In the current work, the impact of the orientation of the BN units in some proposed isomers of iminobora-benzene (B₆C₆N₆H₆) is analyzed. The analysis is oriented toward determining whether the orientation plays an important role in electronic delocalization (aromaticity). The alternation of the BN units generates several isomers, which were built arbitrarily and systematically with the main goal of measuring their respective electronic delocalization. For the analysis of aromaticity, multiple methodologies (AdNDP, AV1245, AVmin, ELF, LOL, MICD, and B^ind) were employed, all of which produced consistent trends. Moreover, the alternation of the BN units affects not only electronic delocalization but also relative stability, with relative energy values of up to 85 kcal/mol observed among the isomers. Interestingly, the most aromatic isomer is the least stable isomer, while the most stable isomer is, with some methodologies, the least aromatic.
