Abstract
Hydrazo compounds have displayed significant roles in both biological and physical aspects, such as spinamycin as a potent growth inhibitor against fungi and rat sarcoma cells, hydrazo tocopherol as a component of vitamin E, and electron-rich hydrazo-linked triazines as energetic materials. In this study, a metal-free approach was proposed for the synthesis of hydrazo-linked 5-(4- aryl)-1H-1,2,4-triazoles. The methods for the synthesis of 5-(4-aryl)-1H-1,2,4-triazoles initiated by the reaction of aldehyde with semicarbazide. The resulted compound, 5-(4-aryl)-1H-1,2,4-triazol-3- ol, upon reaction with phosphorous oxychloride yielded 3-chloro-5-(4-aryl)-1H-1,2,4-triazoles. These synthesized compounds upon fusión with various aryl and hetero aryl substituted hydrazines provided desired hydrazo moieties. Synthesized hydrazo compounds were characterized by spectroscopic techniques, viz. 1H-NMR, FT-IR and mass spectrometry. In this study, a series of novel hydrazo- linked 5-(4-aryl)-1H-1,2,4-triazoles were synthesized. The methodology proposed in this study eliminates the use of complicated procedures and heavy metals.
