Amidoselenation and Amidotelluration of Alkenes using Oxygen as Terminal Oxidant

A protocol has been established for oxygen-mediated amidoselenation and amidotelluration of alkenes under mild conditions. This method provides a simple route to a series of structurally diverse β-amido selenides and β-amido tellurides in moderate to high yields. The wide substrate scope, good functional group tolerance, ease of large-scale preparation and potential for product derivatization make this reaction attractive for the synthesis of nitrogen-, selenium- and tellurium-containing molecules.
