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.

A new synthesis of μ-oxo dimeric iron(III) porphyrins from meso-tetraarylporphyrins in one-pot procedure is reported. μ-oxo dimeric iron(III) porphyrin was obtained in high yield (up to 93%) from the reaction of meso-tetraarylporphyrin with ferrous chloride in DMF at pH 8–11. Compared with other synthetic methods of μ-oxo dimeric iron(III) porphyrin from meso-tetraarylporphyrins, the one-pot procedure has higher yields of μ-oxo dimeric iron(III) porphyrins and is a simpler and more convenient procedure. In order to evaluate the range of applicability of this method, μ-oxo dimeric iron(III) porphyrins with different substituents were prepared by the reaction of the corresponding meso-tetraarylporphyrins with ferrous chloride. The results showed that it was possible to apply this one-pot procedure to the synthesis of other μ-oxo dimeric iron porphyrins in excellent yields. A mechanism for the formation of μ-oxo dimeric iron porphyrins was proposed based on the reaction intermediates characterized by HPLC and UV-vis methods.

Me3Si-/Ph2P(O)-protected ethynes were successfully transformed to unsymmetrical arylethynes via a one-pot Ph2P(O)-deprotection/ [Pd(dppf)Cl2]-catalysed coupling and one-pot Me3Si-deprotection/Sonogashira coupling under mild conditions and in high yield. Unsymmetrical phenylethynes, unsymmetrical extended phenylene ethynylenes and unsymmetrical anthrylethynes were successfully synthesised in good to excellent yields.

Alum (KAl(SO4)2·12H2O) performs as a novel catalyst for the synthesis of 2-arylbenzothiazoles and 2-arylbenzoxazole from o-aminothiophenol and o-aminophenol with various substituted aldehydes in good to excellent isolated yields (85–95%) using water as a solvent at ambient temperature. Several solvents were examined for this reaction; however, in terms of reaction yield and time, water was found to be the optimum solvent. The remarkable advantages offered by this method are an inexpensive and easily available catalyst, a simple procedure, mild conditions, much faster (60–90 min) reactions, and good to excellent yields of products.
