Abstract
Iridium dimer complexes were found to catalyze the [3 + 2] cycloaddition reaction of azides with bromoalkynes, yielding 1,5-disubstituted 4-bromo-1,2,3-triazoles in reasonable to excellent yields under mild conditions. The reaction offers a direct route to new 1,4,5-trisubstituted triazoles.
