Gold(I)-Catalyzed Aminohalogenation of Fluorinated N'-Aryl-N-Propargyl Amidines for the Synthesis of Imidazole Derivatives under Mild Conditions

A procedure for the synthesis of fluorinated imidazole derivatives from propargyl amidines has been developed. Under gold(I) catalysis, propargyl amidines were converted into 5-fluoromethyl imidazoles in the presence of Selectfluor through a cascade cycli
