  This theoretical reactivity study was conducted on six molecules of a series of halogen-substituted Imidazole-Thiosemicarbazides (ITS) using density functional theory, at the B3LYP/6-31+G (d, p) level. Analysis of the thermodynamic formation quantities confirmed the formation and existence of the series of molecules studied. The study of the boundary molecular orbitals, including the energy gap (ΔE), electronegativity (?), chemical hardness (η) and electrophilicity index (ω) provided a better overview of the molecular properties. Thus, the compounds ITS 1 and ITS 4 which have the lowest energy gaps between the boundary orbitals are the most reactive and the least stable. Furthermore, ITS 1 is the softest of the compounds studied. The analysis of the local descriptors and the isodensity map allowed us to identify the N14 nitrogen atom as the preferred electrophilic atta.. Read More»
