Thion- und Dithioester, XXIV Synthese von Tetrathiooxalestern

Hartke, Klaus,Kissel, Thomas,Quante, Josef,Matusch, Rudolf

, p. 1898 - 1906 (2007/10/02)

Reduction of carbon disulfide with potassium in dimethylformamide and subsequent alkylation yields the isotrithiones 2, which have been desulfurised with mercury acetate to give the 1,3-dithiol-2-ones 3. 2a is also available by a stepwise synthesis starting with methyl (methylthio)dithioacetate (6).The photochemical decarbonylation of 4,5-bis(methylthio)-1,3-dithiol-2-one (3a) leads to the formation of dimethyl tetrathiooxalate (11a).In solution 11a is in equilibrium with its dimer 13.Cyclic tetrathiooxalates are probably unstable at room temperature.
