Although 1,2-diamines fail to cyclise with urea, phosgene or 1,1'-carbonyl diimidazole, they react with carbon disulphide to give the corresponding imidazolidine-2-thiones.These undergo clean diacylation to give 1,3-diacylimidazolidine-2-thiones which are

The title compounds are readily prepared in three steps via the corresponding 1,3-diacylimidazolidine-2-thiones. The final step involves the novel use of mercury (II) acetate for the conversion of thioureas to ureas.
