O-(Alkoxycarbonyl)-N-arylhydroxylamines were efficiently converted to 2-aminophenol derivatives by cationic cobalt catalysts at 30 °C. The results of O-labeling experiments suggested that rearrangement of the alkoxycarbonyl group from the aniline nitrogen to the ortho position proceeded in an unprecedented [1,3] manner.
O-(烷氧基羰基)-N-芳基羟胺在 30°C 下被阳离子钴催化剂有效地转化为 2-氨基酚衍生物。O 标记实验的结果表明，烷氧基羰基基团从未有过的[1,3]方式从苯胺氮原子重排到邻位。
