Abstract

Among the ligands that have donor atoms, such as nitrogen and sulfur, thiosemicarbazones are considered important ligands due to their flexibility and sensitivity toward various metal ions. The presence of donor atoms such as oxygen (O), nitrogen (N), and sulfur (S) in the composition of thiosemicarbazone ligands led to different coordination forms. In the same way, the presence of different groups, such as methyl, and phenyl in the terminal N-position, can change the coordination state and catalytic properties of the complexes. These compounds are of great interest due to their simple preparation method, the formation of excellent complexes of not only transition elements but non-transition p-elements, the interesting structural features of their complexes, and the possibility of their catalytic application. In this review article, we will investigate the catalytic application of transition metal complexes in the implementation of various organic reactions.
