Abstract
|
In this research, firstly, preparation and characterization of a novel dicationic molten salt, namely N,N,N′,N′-tetramethylethylenediaminium bisulfate ([TMEDA][HSO4]2), by 1H NMR, 13C NMR, FT-IR, mass, thermogravimetry, derivative thermogravimetry and differential thermal analysis data have been reported. Thereafter, utilization of [TMEDA][HSO4]2 as a recyclable catalyst for the solvent-free synthesis of bis(6-amino-1,3-dimethyluracil-5-yl)methanes via the reaction of 6-amino-1,3-dimethyluracil (2 eq.) and arylaldehydes (1 eq.) has been described.
