and efficient approach for the amine-directed dehydrogenative C(sp2)–C(sp3) coupling of arylamines with acetonitrile was reported by using FeCl2 as the catalyst. Substituted anilines, aminopyridines, naphthylamines, and some nitrogen-containing heterocyclic arylamines react with inactive acetonitrile to form the corresponding arylacetonitriles in moderate to good yields. This protocol features nontoxic
报道了一种使用 FeCl 2作为催化剂的芳胺与乙腈的胺定向脱氢 C(sp 2 )-C(sp 3 ) 偶联的新型有效方法。取代的苯胺、氨基吡啶、萘胺和一些含氮杂环芳基胺与惰性乙腈反应生成相应的芳基乙腈,产率适中至高。该协议具有无毒的铁催化、高效的原子经济性、非预功能化的起始材料、良好的区域选择性以及官能团和芳环的良好相容性,为芳基乙腈提供了一种新颖、直接和绿色的方法。
