  • Mixed carboxylato platinum (II) complexes
    Patent number: 4748254
    Abstract: Novel platinum(II) carboxylatocomplexes of the following general formula: ##STR1## wherein R is tetrahydrofurfuryl or cyclo-C.sub.n R".sub.2n-1, R" is H, an alkyl, hydroxyl, n=3-6; R' is --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --, --CH(OH)--, --CH(OH)--CH.sub.2 --, --CH(OH)--CH(OH)--.These compounds possess a clearly pronounced antitumor activity and are readily soluble in water.A process for preparing these compounds comprises reacting K [PtCl.sub.3 NH.sub.3 ] with KI, followed by treatment of the reaction mixture with tetrahydrofurfurylamine or an alicyclic amine and treatment of the resulting mixture of complexes with a silver salt of the formula: Ag.sub.2 (OOC--R'--COO), wherein R' is as identified above.
