The migration of coordinated PtII in the adenine ring was studied in basic aqueous solutions for the isomeric bis(9-methyladenine) complexes: cis-[Pt(NH3)2(9-made-N7)2]2+ (1) and cis-[Pt(NH3)2(9-made-N1)(9-made-N7)]2+ (2). In both compounds, coordina

In aqueous solution, bis(nucleoside) complexes formed by the reaction of cis-[Pt(NH3)2(H2O)2]2+ with an excess of either adenosine (ado) or a mixture of adenosine and guanosine (guo) undergo a slow N7--> N1 linkage isomerisation in the adenine moiety

Linkage Isomerization in PtII–9-Methyladenine Complexes
Autor: Jorma Arpalahti, Satu Molander, Karel D. Klika
Publikováno v: European Journal of Inorganic Chemistry. 2000:1007-1013
Bis(9-methyladenine) complexes of cis-PtII(NH3)2 undergo slow linkage isomerization from the N7 to the N1 site in aqueous solution at elevated temperatures. The ratio of the isomeric complexes during the isomerization process indicates that whilst Pt

Dynamic processes in platinum(II)–adenosine complexes. Preparation, NMR spectroscopic characterisation and crystal structure of isomeric PtII(dien)–adenosine complexes
Autor: Raikko Kivekäs, Reijo Sillanpää, Jorma Arpalahti, Karel D. Klika
Publikováno v: Journal of the Chemical Society, Dalton Transactions. :1397-1402
The distribution of aquated PtII(dien) between the adenosine N1 and N7 sites has been found to be affected in aqueous solution not only by lowering the pH, but also by equilibration of the mixture of PtII and nucleoside at high temperature. In the fo
