Symmetrical and unsymmetrical N,N’-disubstituted as well as trisubstituted ureas/thioureas by the hydroamination of isocyanates/isothiocyanates, and various phosphathioureas by the hydrophosphination of isothiocyanates have been synthesized in good to excellent yields under catalyst-free and mild conditions. This protocol is also applicable for the efficient synthesis of chiral ureas and thioureas and common herbicides, such as fenuron and monuron.

An efficient, mild, and environmentally friendly route has been developed for the synthesis of unsymmetrical thiourea derivatives in moderate yields by the reaction of tertiary aromatic and aliphatic amines with phenyl-iso-thiocyanate in the presence of N-ZnO as a photocatalyst under visible-light irradiation. This method provides a pathway to activate the tertiary aromatic and aliphatic aminesviaC-N bond cleavage.
