    Description / Table of Contents: Surprising Reactions on O-Methyl-1,1-dithiooxalatesThe O-methyl-1,1-dithiooxalate ligand (i-dtoMe) reacts with metalII-acetylacetonates of d8 metal centers (NiII, PdII) forming mononuclear mixed ligand complexes with two remarkable aspects: The formation of a perthioligand, first time described for thiooxalates, and the first example of a nucleophilic attack of a CH-acidic compound (acetylacetonate) on dithiocarbon of coordinated dithiocompounds (here i-dtoMe). X-ray structure is shown for Ph4P[(ptoMe)Ni(i-dtoMeacac)].
    Notes: O-Methyl-1,1-dithiooxalat (i-dtoMe) reagiert mit Acetylacetonatkomplexen von d8-Metallen (NiII, PdII) unter Bildung von einkernigen Gemischtligandenkomplexen Ph4P[(ptoMe)M(i-dtoMeacac)] unerwarteter Konstitution. Durch Röntgenkristallstrukturanalyse des NiII-Komplexes konnte erstmals ein nukleophiler Angriff einer CH-aciden Verbindung (Acetylacetonat) am Dithiokohlenstoff einer koordinativ gebundenen Dithioverbindung (i-dtoMe) nachgewiesen werden.Gefunden wurde weiterhin die Entstehung einer Perthiogruppierung, die bisher für Thiooxalate bzw. deren Derivate unbekannt war.
