摘要: An efficient synthesis of 5-organotellanyl-1H-1,2,3-triazole compounds was accomplished through [3+2] cycloaddition reaction 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 products assessed two-dimensional NMR spectroscopic experiments X-ray crystallography.
