  abstract  = {Especially sulphur containing compounds are suitable for the separation of noble metals. 1,2-Dithioethenes are weak chelate-forming ligands and in the case of bis(methylthio)maleo-nitrile the donor power of both of the sulphur atoms is further decreased by the electron withdrawing effect of the cyanogroups. Crowned dithiomaleonitrile are macrocyclic chelate ligands which extract Pd(II) at sufficient rate in a very good yields. The synthesis of the immobilised ligands proceeds from the 2-allyloxy-1,2-propanediol forming the dicar-bon acid which is reduced to the diole. With the help of thionylchloride the dichloro compound is synthe-sized forming the macrocycle together with a dithiolate (1,2-disodium-1,2-dicyanethene-1,2-dithiolate, 1,2-disodium-4-methylbenzene-1,2-dithiolate) at high dilution conditions. The allylsubstituted crown ether is sillylated and the resulting alkoxysilane is immobilised onto activated silica gel. The extraction results with crown ethers are compared with that achieved with the help of substituted ß- diketones and 4-acyl-5-pyrazolones. By modification of the cavity of the macrocyclus the extraction rate increases from the acyclic compound through maleonitrile-dithio-21-crown-7, maleonitrile-dithio-15-crown-5 and maleonitrile-18-crown-6. The best results can be observed at the maleonitrile-dithio-12-crown-4. The rise of the function log D= f(log L) gives the composition of the extracted compounds as 1:1. The separa-tion is unsatisfactory in the case of Ag(I), Hg(II), Pt(II), Tl (I) and the most 3d-elements. Summarizing, a very good separation of palladium from the examined elements can be specified. Additional to the extraction experiments, as well as the crystal structures and by UV spectroscopy the for- mation constants of selected chelates were determined.},
