Abstract

Tetrathiooxalate was originally claimed to result from the reduction of CS₂ with sodium. Jeroschewski demonstrated a practical synthesis of C₂S₄^2- by suppressing its condensation with CS₂. His method involves the electrolytic reduction of CS₂ in the presence of a cation that forms a poorly soluble salt with tetrathiooxalate. Additional features of the Jeroschewski method are the use of low temperatures and dilute solutions, both of which minimize the condensation side reaction. This chapter focuses on a procedure that is an adaptation of Jeroschewski's method, but uses a simpler apparatus. Solid (Et₄N)₂C₂S₄ can be stored under N₂ or in a vacuum for months without decomposition. The most useful check of the purity is by optical spectroscopy. It is soluble in highly polar solvents including water.
