    Description / Table of Contents: Systematic Investigations on the Behaviour of Organotin Compounds towards Liquid sulfur Dioxide. VIII: Reactions of Bis(triorganotin) and Diorganotin Sulfides in Liquid SO2At low temperature, bis(trialkyltin) sulfides 1a-c react in liquid SO2 to yield bis(trialkyltin) thiosulfonates 2a-c and products containing less sulfur. At higher temperatures, mainly oxidation to bis(trialkyltin) sulfates 4a-c takes place; as by-products dialkyltin sulfites 5 and sulfates 6 may result. In contrast, bis(triphenyltin) sulfide (1d) yields the disulfinate 8d and diphenyltin sulfide (9d) independently of conditions. The dialkyltin sulfides 9a, b react with SO2 at room temperature to yield insertion products 10a, b and at 60°C to form sulfites 5a,b. The vibrational spectra of the newly prepared compounds are discussed.
    Notes: Die Bis(trialkylzinn) - sulfide 1a-c reagieren in flüssigem SO2 bei tiefer Temperatur zu Bis(trialkylzinn)-thiosulfonaten 2a-c und schwefelärmeren Produkten. Bei höheren Temperaturen erfolgt vorwiegend Oxidation zu Bis(trialkylzinn)-sulfaten 4a-c; als Nebenprodukte können Dialkylzinn-sulfite 5 und -sulfate 6 entstehen. Bis(triphenylzinn)-sulfid (1d) liefert dagegen unabhängig von den Reaktionsbedingungen das Disulfinat 8d und Diphenylzinn-sulfid (9d) als Endprodukte. Die Dialkylzinn-sulfide 9a,b reagieren mit SO2 bei Raumtemperatur zu den Insertionsprodukten 10a,b und bei 60° zu den sulfiten 5a,b. Die Schwingungsspektren der neu dargestellten Verbindungen werden diskutiert.
