Selective cleavage of an inert C-C bond followed by C-O/N bond formation through a long-distance aryl migrationfrom a carbon to a nitrogen center via Ag catalysis is reported. The migration products were easily converted into γ-hydroxy amines and tetrahydroquinoline derivatives in quantitative yields. Preliminary mechanistic studies indicated a radical pathway.
据报道,惰性 CC 键的选择性裂解,然后通过银催化从碳到氮中心的长距离芳基迁移形成 CO/N 键。迁移产物很容易转化为定量产率的 γ-羟基胺和四氢喹啉衍生物。初步的机理研究表明了一种激进的途径。
