10-phenanthroline-catalyzed direct sulfenylation reactions was reported. In this reaction, heteroarenes such as indoles, and pyrroles serve as nucleophiles by installing a arylthio group at the C3 and C2 position of heterocycles, respectively. With readily accessible and free of unpleasant odor ethyl arylsulfinates as sulfur reagents, the metal-free-catalyzed direct sulfenylation of N-heteroarenes has been
据报道,通过NH 4 I / 1,10-菲咯啉催化的直接亚磺酰基化反应可有效合成N-杂环芳基硫化物。在该反应中,通过在杂环的C 3和C 2位置分别安装芳硫基,使杂芳烃如吲哚和吡咯成为亲核试剂。随着容易获得并且没有令人不愉快的气味的芳基亚磺酸乙酯作为硫试剂,已经开发了无金属催化的N-杂芳烃的直接亚磺酰基化。即使在克规模上,也以中等至优异的产率获得了3-芳硫基吲哚和2-芳硫基吡咯的衍生物。该反应对于广泛的底物是通用的,并且显示出对多种官能团的良好耐受性。
