Abstract
Abstract 3,4-Diphenyl-1H-pyrrolo[2,3-b]pyridine, a useful organic building block, was obtained via a four-step reaction and the structure was determined using FT-IR, 1H NMR, 13C NMR, and mass spectrometry, and the single crystals were characterized using X-ray diffraction analysis. The optimal molecular structure, 1-2 (49.95%), was calculated using density functional theory, and was consistent with the structure determined based on single-crystal diffraction; the relative Gibbs free energy of conformer 1-2 was 0.001255 kcal mol−1. In addition, the molecular electrostatic potentials and frontier molecular orbitals of the title compound were investigated, and surface analysis was performed to further reveal its physicochemical properties.
