- Abstract
In this research, two novel dicationic Brönsted acidic ionic liquids based on diethylamine were synthesized and characterized by various spectroscopic techniques such as Fourier transform infrared spectroscopy, Proton NMR (1H NMR), Carbon-13 NMR (13C NMR), Mass spectrometry as well as Hammett acidity function. The obtained results showed that the dicationic ionic liquid (DIL) to be efficient catalyst in the synthesis of 1, 8-dioxooctahydroxanthenes, 14-aryl-14H-dibenzo [a, j] xanthenes and 1, 8-dioxodecahydroacridines under solvent-free conditions. In addition, two DILs were investigated for their antibacterial activity against gram-positive and gram-negative bacterial strains by the agar diffusion method. Ease of preparation and handling of the catalyst, high yield of products in short reaction times, reusability of the catalyst, as well as high antibacterial activity of DILs are the main advantages of the present method.
