Abstract

A simple one-pot and catalyst-free method is reported for synthesis of some new bipyrazole derivatives by three-component reaction between arylglyoxals, 3-methyl-1H-pyrazol-4(5H)-one and aroylphenylhydrazone derivatives. The reactions were carried out in ethanol as a green solvent in neutral reaction conditions and products were simply isolated by filtering of the precipitated solids in high yields. All products were characterized by their ¹H and ¹³C NMR and IR spectral and elemental analysis data.

期刊介绍： Synthetic Communications presents communications describing new methods, reagents, and other synthetic work pertaining to organic chemistry with sufficient experimental detail to permit reported reactions to be repeated by a chemist reasonably skilled in the art. In addition, the Journal features short, focused review articles discussing topics within its remit of synthetic organic chemistry.
