| Abstract: | An environmentally friendly and economically attractive access to unsymmetrical and symmetrical 1,2-diamines has been developed. Chemoselective N-monoalkylation in water and alcoholic solvents was demonstrated. This method represents a simple and scalable preparation (2-3 steps) of symmetrical and unsymmetrical imidazolidinium salts, precursors of N-Heterocyclic Carbenes. |
