Abstract:
The synthesis of platinum bipy (bipy = 2, 2' – bipyridyl) complexes containing some anionic Group 16 ligands with kinetic studies of the oxidative – addition reaction of MeI to phenoxo platinum (II) complexes are reported. Complexes of the form [ (4- X C6H4E) Pt (bipy) ] ( E = O,S ; X = H,CH3,Cl,Br) are prepared by the reaction of the chloro complex with substituted phenols or substituted thiophenols and KOH in a two-phase system of water and chloroform in the presence of triphenyl phosphonium chloride . Platinum (IV) complexes are formed by oxidative – addition of MeI to the platinum (II) complexes obtained. The complexes were characterized by elemental analysis, uv – visible, i. r, nmr spectroscopy. The x-ray crystal structure of square planar[(bipy)Pt(OC6H4-4-OMe)2] is reported. The reaction of methyl iodide with di(4-ClC6H4O)( 2, 2' - bipyridyl) platinum(II) to give iodo (methyl) di(4-ClC6H4O)( 2, 2' - bipyridyl) platinum(IV) follows the rate law, rate = K2[Pt(4-ClC6H4O)2(2, 2' - bipyridyl)] [MeI] . The values of K2 increase with increasing polarity of the solvent, suggesting a polar transition state for the reaction.
