“…It can function as both an acid and as a base and hence is amphoteric. Many studies on insertion of CS2 have been reported so far using various transition metals complexes such as Ru [4,7], Cu [5], Mn, Re [8], Ni [9], Pt, Pd [10], Rh, Ir [10][11][12], Au [13], U [14], etc. All these transition metals are remarkable in the sense that they display several oxidation states.…”

Carbon disulphide, a versatile ligand with the potential to form complexes with most of the transition metals have the ability to insert into a variety of M-X bonds (X = H, C, N, P, S, Cl or O), of which its insertion into M-O bonds of alkoxides is specific leading to the formation of metal O-alkyl thiocarbonates or dithiocarbonates [1]. Insertion of carbon disulphide into M-H and M-P bonds leading to the formation of dithioformate and phosphoniodithiocarboxylate ligands is common [2]. The complexation of transition metals with σ-donors like phosphines, arsine and stibines having empty d-orbitals of proper symmetry is also known [3]. Moreover, in recent years, research in the area of carbon rich ligands with appreciable π-electron density are gaining more attention because of their good optoelectronic property which take an active part in tuning the electronic properties and stabilizing the complexes. The antioxidant and biological activities of transition metal compounds with dithio-ligands are also known, which can be synthesized by insertion of CS2 into transition metal centers containing carbonyls, arsine, phosphine and cyclopentadienyls. CS2, being an unsaturated electrophile and an abundant source of C1 chemistry, is a useful reagent for insertion into transition metal complexes in presence of other donor ligands producing new and exciting derivatives. It can bond to metal centres in various modes such
