Thermal reaction of various azido esters with tributyltin hydride in refluxing benzene results in smooth production of 3-(tributystannyl)-1-triazene adducts affording cyclized 1,2,3-triazol-4-ones in preference to reduced amines and thence provides a new useful method for the preparation of these triazole derivatives.

Abstract
Thermal reaction of various azido esters with tributyltin hydride in refluxing benzene results in smooth production of 3-(tributystannyl)-1-triazene adducts affording cyclized 1,2,3-triazol-4-ones in preference to reduced amines and thence provides a new useful method for the preparation of these triazole derivatives.File in questo prodotto:
