title: The aromaticity of 5,6-dihydroborauracil, borauracil and benzoborauracil systems.
abstract: The nucleus-independent chemical shift (NICS) indices of aromaticity, calculated for four boron compounds, 4-hydroxy-5,6-dihydroborauracil, 4-hydroxyborauracil, borazine and 4-hydroxybenzoborauracil, and parent uracil, were analyzed in parallel with the NMR properties, in order to learn more about the aromaticity of those heterocyclic systems. The existence of a unique solvent-dependent aromaticity of 4-hydroxyborauracil is indicated.
