Abstract

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 ...
