Synthesis of pyrazole and cumarine derivatives in ionic liquids and nanoparticles effects on reaction

The reaction of malononitrile with carbonyle and ethylorthoacetate compounds gave theMichel intermadiate. The latter compound under ionic liquid and presence of basic nanoparticles ZnO-MgO ready cyclization when treated with hydrazine carboxy malononitrileto give the 1-(isocyanoacetyl)-3-phenyl-1H-pyrazol-5-amine. This compound underwent aseries of heterocyclization to give either coumarin derivatives.
