  The gold(I)-catalyzed synthesis of 2-fluoroalkyl imidazole derivatives was developed. Catalyzed by gold(I), propargyl amidines underwent a 5-exo-dig cyclization to afford 2-fluoroalkyl-5-methyl imidazoles. Also, 2-fluoroalkyl imidazole-5-carbaldehydes were obtained in the presence of NIS. A mechanism investigation manifested the probable process and the carbonyl oxygen derived from O2.

  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 cyclization/fluorination process. In contrast, imidazole‐5‐carbaldehydes were obtained in high yields when N‐iodosuccinimide (NIS) was used as the halogenating

  已经开发了由炔丙基am合成氟化咪唑衍生物的方法。在金（I）催化下，在Selectfluor存在下，通过级联环化/氟化过程将炔丙基am转化为5-氟甲基咪唑。相反，当使用N-碘代琥珀酰亚胺（NIS）作为卤化剂时，可以高产率获得咪唑-5-甲醛。溶剂和光的极性对甲醛的形成有重大影响。这些转变显示出极好的功能组耐受性。具有吸电子基团的未氟化底物也进行了氨基卤代反应，从而以高收率得到了相应的产物。机理研究揭示了这些转变的一般途径。

  A simple and efficient method of iodine-mediated aminohalogenation-oxidation of fluorinated N’-propargyl amidines to synthesize 2-fluoroalkyl imidazole-5-carbaldehydes was developed. This method showed good functional group compatibility and wide substrate scope, as variety of substituted substrates proceeded smoothly to give the corresponding products in moderate to excellent yields. And this method was also suitable to unfluorinated substrates. Fluorinated allyl amidines used as starting materials, aminohalogenated products were obtained as the final products. Studies on the mechanism indicated that the carbonylation proceeded via 5-iodomethyl imidazole intermediate, and the carbonyl oxygen atom was demonstrated that originated from dioxygen.
