Abstract

Promoted by KOH under ball milling, anilines were efficiently transformed into isothiocyanates (in presence of 5.0 equiv. CS2) or symmetrical thioureas (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 unsymmetrical thioureas.
