ON THE COMPLEX-FORMATION OF NOVEL BIS(PHE NOXYALKYL)SULFANE PODANDS WITH AG-1 AND HG-II

Novel bis(phenoxyalkyl)sulfane podands were synthesized and characteri zed in view of their complexing properties toward Ag-I and Hg-II by li quid-liquid extraction investigations using the two-phase system metal salt(AgNO3, HgCl2)-picric acid-H2O/podand-chloroform. A pronounced st ructure influence on the extraction properties has been observed in ca se of Ag-I, whereas generally the complex formation tendency toward Hg -II is limited. ydroxy-3-oxapentyloxy)-3-phenoxy-prop-2-yl]sulfane 4c gives the highest extractabilities for Ag-I. Molecular modeling of the podands and their A(I) and Hg-II complexes shows significant differen ces of the complex structures and indicates therewith the reasons of t he different complexing properties.
