    Description / Table of Contents: Electrophilic Addition of Disulfur Dichloride to Alkynes, IV1). - Some Derivatives of the (1:1)-Adducts of Disulfur Dichloride and AlkynesIn dimethylformamide, which serves as a solvent and a catalyst, disulfur dichloride adds to alkynes to yield both divinyl sulfides and benzothiophenes. After oxidation of the resulting sulfides to the corresponding sulfones, the chlorine atoms located on the vinyl groups can be substituted by other nucleophilic agents.
    Notes: Dischwefeldichlorid addiert sich an substituierte Alkine unter Dimethylformamid-Katalyse und bildet sowohl Divinylsulfide als auch Benzothiophene. Nach Oxidation der Sulfide zu den entsprechenden Sulfonen können die vinylständigen Chloratome durch andere Nucleophile substituiert werden.

    Description / Table of Contents: Reaction of Aryl Alkyl Ketones with Dimorpholinodisulfide. - Contribution to the Willgerodt-Kindler-SynthesisSubstitution of the normally used sulfur-amine mixtures by dimorpholinodisulfide 1 in a modified Willgerodt-Kindler-reaction with the ketones 2a-d affords the products 5, 6 and 7. The fragmentation reaction of 1, occurring as a side reaction in the modified Willgerodt-Kindler-reaction affords the compounds 3 and 4.
    Notes: Ersetzt man die bisher üblichen Schwefel-Amin-Gemische durch Dimorpholinodisulfid 1 und wendet dieses in einer modifizierten Willgerodt-Kindler-Reaktion auf die Ketone 2a-d an, so können die Produkte 5, 6 und 7 isoliert werden. Die Fragmentierungsreaktion von 1, die als Konkurrenzreaktion bei den obengenannten Umsetzungen auftritt, führt zu den Verbindungen 3 und 4.
