Synthesis of Diethoxy Arylphosphoryl Functionalyzed Fully Substituted 5‑Triazenyl-1,2,3-triazoles via Chelation-Assisted Interrupted Domino Reactions of Ortho-Azidophosphonates with Copper(I) Alkynes
We describe the synthesis of 1,4-(disubstituted)-5-triazenyl-1,2,3-triazoles bearing diethoxy arylphosphoryl moieties via a domino reaction between ortho-azidophosphonates and premade copper(I) alkynydes involving a chelation-assisted [3+2] cycloaddition followed by interception of the copper(I) triazolide generated by the azide. The resulting dicopper(I) triazoletriazenide complex has been characterized through X-ray diffraction.
