4-(2-R-Aryl)-1,2,3-chalcogenadiazoles in the synthesis of fused heterocycles

Abstract

The review generalizes and systemizes published data on the synthesis and chemical transformations of 4-(2-R-aryl)-1,2,3-thia- and -selenadiazoles. Powerful synthetic potential of 4-(2-R-aryl)-1,2,3-chalcogenadiazoles ensures their use in the synthesis of various heterocyclic compounds, such as 1-benzofurans, indoles, 1-benzothiophenes, 1-benzoselenophenes, and their more complex derivatives.
