    Description / Table of Contents: Metal Chelates of Unsaturated 1,2-DithioethersThe dialkyl- and diaralkyldithioethers of ethylenebisthiol (edt) and xylenedithiol form cationic 1:2 chelates with the d8-metal ions AgI and CuI, which have been isolated and characterized. PdII- and PtII-halides yield neutral mixed ligand complexes of the type Me (L—L) X2 (L—L = dithioether, X = halogen). The dibenzyldithioether of edt is cleaved oxidatively by CuII and yields dibenzyldisulfide, CuI and an unidentified product.
    Notes: Dialkyl- und Dibenzyldithioäther von Äthylendithiol (edt) und Xyloldithiol (xdt) bilden mit AgI und CuI kationische 1:2-Chelate, welche isoliert und charakterisiert wurden. PdII und PtII ergeben mit diesen Liganden neutrale Chelate des Typs Me(L—L)X2 (L—L = Ligand; X = Halogen). Bei der Umsetzung von Dibenzyldithioäthylen mit CuII findet eine Oxydation des Liganden statt, und man erhält CuI, Dibenzyldisulfid und ein undefiniertes Produkt.
