METHOD FOR PRODUCING PLATINUM COMPLEXES (IV) WITH AMINONITROXYLE RADICALS Russian patent published in 2017 - IPC C01G55/00 

FIELD: chemistry.

SUBSTANCE: invention relates to producing platinum complexes (IV) with amino-nitroxyle radicals, the resulting products and use thereof. Claimed a method for producing platinum complexes (IV) with amino-nitroxyle radicals of a general formula 1 , where A¹ - a heterocyclic piperidine nitroxyle radical with amino group, A² - NH₃, X - haloid ligands or X+X - dicarboxylate ligands, Y - hydroxy- or acyloxy-ligands -OCOR, enabling interactions between platinum complexes (II) M[Pt(NH₃)Cl₃], where M - alkaline cation, and 4-amino-2,2,6,6-tetramethylpiperidine resulting in intermediate mixed ligand complexes of platinum (II) followed by their oxidizing and acylation into complexes of platinum (IV), wherein substituted amine is a sterically hindered heterocyclic amine 4-amino-2,2,6,6-tetramethylpiperidine; organic peracids are used for oxidation in a polar organic solvent, acylation is a catalyst-free reaction or 4-dimethylaminopyridine is used as catalyst, followed by recovery of the target product.

EFFECT: cost-effective and efficient method for producing platinum complexes (IV) with amino-nitroxyle radicals.
