| 摘 要： | Applications of samarium diiodide as a mild, neutral, selective and versatile single-electron transfer reducing and coupling reagent in organic synthesis have grown significantly in the last decade1. It is well known that both nitro compounds2a and azide compounds2b can be easily reduced by SmI2 to the corresponding amines. Little attention has been given to the intermediates derived from nitro or azide groups by treatment of SmI2, which may lead to reactions difficult to accomplish by other …
