Synthesis of N-(iodophenyl)-amides via an unprecedented Ullmann–Finkelstein tandem reaction

Using a new Ullmann–Finkelstein tandem reaction, N-(iodophenyl)-amides were synthesized from the corresponding amides and iodo-bromobenzenes. The catalyst/ligand couple CuI/N,N′-dimethyl-cyclohexane-1,2-diamine was used for this reaction in dioxane with K3PO4 as base.
