The novel 2-(difuoromethyl)-3-methylchromone, 2-(dichloromethyl)-3-methylchromone, and 3-methyl-2-(perfuoroethyl)-chromone were synthesized by a one-pot method and characterized through MS spectrometry, cyclic voltammetry, and vibrational (IR, Raman), UV?Vis, fuorescence, and NMR (1H, 13C, and 19F) spectroscopy. The crystal structure of 2-(difuoromethyl)-3-methylchromone and 2-(dichloromethyl)-3-methylchromone determined by X-ray difraction methods were used to calculate their intermolecular interactions and crystal lattice energies together with the Hirshfeld surfaceanalysis.
