摘要
Aryl azides 1 were treated with allenylmagnesium bromide (2) to generate 1,5-disubstituted butynyl-1H-1,2,3-triazoles 3 in a domino fashion, which upon Cu-1-catalyzed 1,3-dipolar cycloaddition with aryl azides 4 afforded novel bis-1H-1,2,3-triazoles 5 in quantitative yields (Scheme 1 and Table).
