Cisplatin ligand substitution equation
WebWe found that when Pt (II) complexes are reacted with sulfur ligands both quickly lose their halide ligands and then the resulting cis- [Pt (L) 2 (NH 3) 2] species loses ammonia upon … WebThe synthesis of cisplatin is shown in the figure below. In tetrachloroplatinate {\rm { (II)}} (II) , ammonia substitutes the leaving chlorine ligand because of the trans directing effect of chlorine. Similarly, other chlorine trans to chlorine atom is substituted by another incoming ammonia ligand leading to the formation of cis platin.
