Cleavage of N−O Bonds Promoted by Samarium Diiodide: Reduction of Free or N-Acylated O-Alkylhydroxylamines

The authors examined the ability of samarium diiodide to promote N-O cleavage in N-acylated O-alkylhydroxylamines. The reaction offers a chemoselective and high-yield route to the preparation of corresponding amines or amides. 12 refs., 1 tab.
