The synthesis of some new chalcones is described. A series of the pyrazole and pyrazoline type derivatives were obtained by the condensation of the chalcones with hydrazine and phenylhydrazine. All compounds were characterized using NMR, IR, MS techniques. Computer molecular modeling assisted for NMR spectral analysis.
