Synthesis of New Pyrazole Derivatives Using Vinamidinium Salts abstract
Novel pyrazole derivatives 2-7 are synthesized by the reaction of 2-substituted 1,3-bis(dimethylamino)-trimethinium salts with phenyl hydrazine in acetonitrile as the solvent. This method has some advantages of high yields (78-85%), simplicity of the process and easy of control. The ultraviolet spectral behavior of the synthesized compounds is examined in CDCl3 and their structures were characterized by elemental analysis, FTIR, 1H and 13C NMR and Mass spectra.
