Benign synthesis of unsymmetrical arylurea derivatives using 3-substituted dioxazolones as isocyanate surrogates

A phosgene- and metal-free synthesis of unsymmetrical arylurea derivatives utilizing 3-substituted dioxazolones and commercially available amines has been developed. The 3-substituted dioxazolones serve as the precursors of the in situ generated isocyanate intermediates in the presence of non-toxic...
