Bidentate phosphine ligands have been prepared on polystyrene beads modified with polyether dendron spacers. When complexed to Pd0, these systems exhibited a negative dendritic effect on Heck catalysis (contrary to the analogous monodentate phosphine systems), but mostly a positive influence on carbonylation. This opposite influence of the dendronization falls into line with other differences in the optimal ligand structure for the two reactions. The negative effect on the Heck catalysis with bidentate phosphines may indicate that dendrimer-induced reduction in the cross-linking upon Pd complexation is responsible for the positive effect in the corresponding monodentate phosphine systems.

The invention is related to copper and platin compounds and synthesis method of compounds which are active in cancer cells that show resistance particularly against cisplatin, having a wider effect spectrum in comparison to cisplatin, and a lower toxicity in comparison to cisplatin, having reduced side effects, which can be used as a potential antitumor drug, having anti cancer (cancer treating) and anti oxidant effects, comprising DNA targeted mono and binuclear platin and copper platin complexes and similar functional groups.
