Synthesis, physico-chemical properties of 3-thio and 3-thio -4-amino derivatives of 1,2,4-triazole

Abstract

Modern medicine and pharmacy has at its disposal highly efficient synthetic drugs. Large extent of these drugs accounted for derivatives of 1,2,4-triazole.
 The purpose of the work was an attempt to summarize the literature in recent years related to the methods of synthesis and study of physico-chemical properties 3-thio- and 3-thio-4-amino derivatives of 1,2,4-triazole.
 Studies national scientists in recent years indicates prospects of the search in this direction, since this class of organic compounds is interest not only to scientists pharmaceutical, medical and veterinary field, but also among researchers of engineering, metallurgical and agricultural areas. 1,2,4-triazole derivatives are also widely used in practice for optical materials, photosensitizers are used as coloring agents, antioxidants, additives for fuels and oils, some of which are widely used as corrosion inhibitors for controlling various pests in agriculture. In addition, 1,2,4-triazole derivatives belong to the class low toxic or essentially non-toxic substances.
 The presence of a growing number of publications about methods of synthesis, reactions, physico-chemical and biological properties of 1,2,4-triazole, inspires scientists around the world search for perspective molecules of substituted 1,2,4-triazole. It should be noted that in spite of a sufficient amount of information about the derivatives of 1,2,4-triazole, some issues related to the generalization of data in the literature synthesis presented insufficient.
