With Replacement of Both Dithiocarbonate Groups

When tellurium bis[6)-ethyl dithiocarbonate] was heated in methanol with sodium dithiocarbamates, tellurium bis[dithiocarbamates] were formed.  

The dithiocarbonate groups were also exchanged for dithiocarbamate groups when tellurium bis[0-alkyl dithiocarbonates] were heated with bis[dithiocarbamyl] disulfides in chloroform.  

Tellurium bis[0-ethyl dithiocarbonate] decomposed upon exposure to aqueous-ethanolic sodium hydroxide to tellurium and tellurite.  

The tris[0-ethyl dithiocarbonato]tellurate(II) anion was obtained in the form of its tetraethylammonium or tetraphenylarsonium salt, when tellurium bis[0-ethyl dithiocarbonate] was combined with additional O-ethyl dithiocarbonate in warm methanoP or ethanol.  

Tetraphenylarsonium Tri [0-ethyl dithiocarbonato]tellnrate(ll) 580 mg (4.00 mmol) of potassium O-elhyl dithiocarbonate and 1.68 g (4.00 mmol) of tetraphenylarsonium chloride are dissolved in 40 ml of warm methanol, 1.48 g (4.0 mmol) of solid tellurium bis[0-ethyl dithiocarbonate] are added, the mixture is stirred for a few minutes, and then filtered through a fine glass frit into a flask cooled at — 10°. The filtrate is stored in a freezer overnight, the yellow crystals are collected, and recrystallized from warm (45°) methanol yield 0.25 g (7%) m.p. not reported.
