AbstractThe highly effectual synthesis of 4,6-diarylpyrimidin-2(1H)-ones via the one-pot multicomponent reaction of acetophenones with arylaldehydes and urea in the presence of trimethylsilyl chloride and a catalytic amount of the ionic liquid N,N,N′,N′-tetramethylethylenediaminium-N,N′-disulfonic acid hydrogen sulfate ([TMEDSA][HSO4]2) under solvent-free conditions has been described. The reaction results and conditions of the catalytic system have been compared with previously reported catalysts. [TMEDSA][HSO4]2 afforded better results in comparison with the reported catalysts in terms of one or more of these factors: yield, temperature, the reaction media, time, and generality. Moreover, a plausible reaction mechanism based on dual functionality of the catalyst has been proposed.

AbstractIn this research, initial production and characterization of a novel Brønsted-acidic ionic liquid, namely,N,N,N′,N′-tetramethylethylenediaminium-N,N′-disulfonic acid hydrogen sulfate ([TMEDSA][HSO4]2), has been described (characterization was achieved using Fourier-transform infrared spectroscopy,1H nuclear magnetic resonance (NMR),13C NMR, and mass and thermal gravimetric spectra). Thereafter, utilization of [TMEDSA][HSO4]2as a highly effectual catalyst for the synthesis of 4,4′-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) derivatives through the one-pot pseudo five-component reaction of phenylhydrazine (2 eq.) with ethyl acetoacetate (2 eq.) and arylaldehydes (1 eq.) in relatively mild conditions, has been reported.
