WebIron tris (diethyldithiocarbamate), a black solid that is soluble in organic solvents, is a representative complex of diethyldithiocarbamate. Oxidation of sodium diethyldithiocarbamate gives the disulfide, also called a thiuram disulfide (Et = ethyl ): 2 NaS2CNEt2 + I2 → (S2CNEt2)2 + 2 NaI. Dithiocarbamates are nucleophiles and thus … WebAbstract. Dithiocarbamates are highly versatile mono-anionic chelating ligands which form stable complexes with all the transition elements and also the majority of main group, lanthanide and actinide elements. They are easily prepared from primary or secondary amines and depending upon the nature of the cation can show good solubility in water ...

In 1993, the JMPR derived an ADI of 0–0.03 mg/kg bw for dithiocarbamate pesticides as mancozeb and maneb based on thyroid toxicity. For their metabolite ethylenethiourea (ETU), an ADI of 0– 0.004 mg/kg bw has been allocated.
