anilines were efficiently transformed into isothiocyanates (in presence of 5.0 equiv. CS2) or symmetricalthioureas (in presence of 1.0 equiv. CS2), without using any other harsh or toxic decomposition reagent. Some in situ generated isothiocyanates can directly “click” with other amines to afford unsymmetricalthioureas.
