ResumoN-(Trialkylstannyl)-4-mono- or 4,5-disubtituted 1,2,3-triazoles have been prepared by the 1,3-cycloaddition of tri-n-butyltin azide to alkynes and by the condensation of 1,2,3-triazoles with bis(tri-n-butyltin) oxide or trimethyltin hydroxide. The trialkyltin group has been shown to be attached to the 2-nitrogen of the 1,2,3-triazole ring. N-Tri-n-butyltin derivatives of 3-phenylpyrazole, 4-phenylimidazole and 3-phenyl-1,2,4-triazole have been prepared by the condensation of bis(tri-n-butyltin)oxide with the corresponding azoles, the tri-n-butyltin group becoming attached to the 1-nitrogen atom of the latter.
