Mefenamic acid (0.40 mmol) was dissolved in methanol (15 mL) followed by the addition of KOH (0.40 mmol). After 60 min of stirring, the resulting solution was slowly added to an aqueous solution of [PdCl2(bipy)] (0.20 mmol). After 40 min of constant stirring, the yellow solid obtained was collected by filtration, washed with ethanol and dried in a desiccator with P4O10. The yield was 63%. Anal. Calc. for [Pd(C15H14NO2)2(bipy)] (%): C 64.6; H 4.88;N 7.54. Found: C 63.3; H 4.74; N 7.62. The complex is soluble inchloroform and insoluble in water and DMSO. As already observed for the Pd-tra complex, no single crystals were obtained to perform an X ray structural characterization. The [PdCl2(bipy)] complexused as a precursor in the synthesis of Pd-mef was synthesized as described in the literature [21].

The mixture was stirred overnight in the dark,at room temperature. The precipitate AgCl was removed by filtrationand the resulting pale yellow solution of [PtCl(bipy)(DMF)]ClO4 was kept in a refrigerator to cool down. A suspension of[PdCl2(bipy)] complex (73.5 mg, 0.220 mmol) in 10 cm3 of DMFwas heated with stirring at 303-313 K for about 30 min. After that,the solution of 1,6-diaminohexane (25.5 mg, 0.220 mmol) in 5 cm3DMF was added dropwise. The mixture was stirred at room temperaturefor 5 h in the dark. The filtrate [PtCl(bipy)(DMF)]ClO4was added to the resulting mixture. The clear yellow solutionwas stirred for 3 h at 323 K and then for 24 h at room temperature.The solution was then evaporated and the residue washed withether.
