containing compounds through a number of methods; however, direct introduction of N- and O-functionality remains challenging. Presented herein is a general method to allow for the simultaneous installation of N- and O-functionality to construct unexplored N–O heterocyclic and amino-alcohol scaffolds. This transformation uses earth abundant copper salts to facilitate the formation of a carbon-centered radical

Provided is a method for producing an organic tellurium compound that enables the production of an organic tellurium compound in high yield using metallic tellurium as a source material and produces less amount of side products. A method for producing an organic tellurium compound includes the steps of: (A) reacting metallic tellurium with a compound represented by a general formula (1) below; and (B) reacting a compound obtained by the step (A) with an organic halogen compound, the metallic tellurium having a copper content of less than 100 ppm,
