Abstract: An efficient synthesis of 5-organotellanyl-1H-1,2,3-triazole compounds was accomplished through [3+2] cycloaddition reaction of organic azides and (organotellanyl)alkynes. Additionally, 5-organotellanyl-1H-1,2,3-triazoles were readily functionalized at the 5-position by using a Sonogashira cross-coupling reaction, leading to highly functionalised triazoles. The regiochemistry of the products was assessed by two-dimensional NMR spectroscopic experiments and X-ray crystallography.
