Cisplatin ligand substitution equation
WebThe equation for this reaction is2CH3CHO + O2 2CH3COOH This redox reaction is slow at room temperature but speeds up in the presence of cobalt compounds. Explain why a cobalt compound is able to act as a catalyst for this process. Illustrate your explanation with two WebAssociative ligand substitution is common for complexes with 16 total electrons or fewer. The reaction is characterized by a second-order rate law, the possibility of solvent participation, and a trigonal bipyramidal intermediate that is often fluxional.

WebAug 1, 2024 · For both cis - [PtCl (L) (NH 3) 2] and cis - [PtI (L) (NH 3) 2 ], the second substitution of halide resulted to be moderately endergonic for cysteine and methionine and barely exergonic for histidine models with reaction free energies, respectively, of +6.5 and +3.8 and −0.2 for the chloro and +7.7, +1.9 and −4.6 kcal mol −1 for the iodo complex. WebActivated [PtCl (NH 3) 2 (L) (H 2 O)] + ions dissociate by the loss of either H 2 O or L, the former process implying a ligand substitution event. IRMPD spectroscopy has thus …
WebIn the case of imidazole, again cis- [PtCl 2 (NH 3) 2] and cis- [PtI 2 (NH 3) 2] quickly lose their halide ligands but the resulting cis- [Pt (L) 2 (NH 3) 2] species does not lose ammonia by reaction with excess imidazole. WebCisplatin (cisPt) is one of the strongest anticancer agents with proven clinical activity against a wide range of solid tumors. Its mode of action has been linked to its ability to crosslink with the canonical purine bases, primarily with guanine. Theoretical studies performed at the molecular level suggest that such nonspecific interactions can also take …
