Hypervalent Iodine in Synthesis 57: An Efficient Method for the synthesis of N-Arylimidazoles by the Cobalt-Catalysed Coupling of Diaryliodonium Salts with Imidazoles †
Cobalt-catalysed N-arylation of imidazole with diaryliodonium salt can be accomplished using Co(OAC)2 as a catalyst and K2CO3 as a base in DMF at 80 °C in high yields.
