In a 1percent dioxane-water solvent in the presence of Hg2+ ions thiocarbamates p-RC6H4NHC(S)OEt (R = MeO, Me, H, F) rapidly form complexes of 2 thiocarbamate: 1 Hg2+ stoichiometry.In the presence of an excess of Hg2+ ions partial conversion to the 2:2-complexes probably occurs which decompose to the corresponding carbamates (p-RC6H4NHCO2Et) and HgS.With R = NO2 the 2:2 complex is dominant even at low Hg2+ ion concentrations, and desulfurisation is then independent of
