  Kinetics of the mercury(II) ion-promoted desulfurisation of thiocarbamates in aqueous solution

  摘要：

  In a 1% 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-RCH4NHCO2Et) and HgS. With R = NO2 the 2:2 complex is dominant even at low Hg2+ ion concentrations, and desulfurisation is then independent of [Hg2+] . Electron-withdrawal by R favours the 2:2 complex but decreases its rate of decomposition to products. The effects of changes in the hydrogen ion concentration suggest that ionisation of N-bound protons in the complexes favours reaction. A mechanism is suggested. The kinetic behaviour is somewhat similar to that found previously for thiobenzamides, but the new results suggest the mechanism previously proposed may need revision.

• Synthesis of Sulfonylisoureas via Sulfo-Click Reactions
  作者：Moritz Ottenbruch、Fabian Mohr、Stefan F. Kirsch

  日期：2020.3

  The synthesis of sulfonylisoureas from thiocarbamates and sulfonyl azides via a new variant of the sulfo-click reaction is reported. Water was found to be the environmentally benign solvent of choice over various other solvents tested, and the use of any additives was not required to obtain complete conversion. The experimentally simple reaction­ tolerates a broad range of electron-donating and electron-withdrawing
