The inherent reactivity of thiocarbohydrazides and thiosemicarbazides makes them valuable as building blocks for the synthesis of other heterocyclic motifs. This review article discusses the recent applications of classes of compounds in syntheses of five‐membered to seven‐membered heterocycles of biological activities and remarkable number of metal complexes. Many previous reviews dealt with the reactivity of either thiosemicarbazides or thiocarbohydrazides. However, a large number of publications have recently dealt with the reactivity of thiosemicarbazides and thiocarbohydrazides. Consequently, we have found that it is of importance to shed new light on these interesting molecules.
