In an effort to avoid the hazards of isolating and handling azides in click chemistry, many groups have turned to in situ generation of azides from halide precursors. This option is readily accomplished for alkyl azides, but is more challenging for aryl azides. In this paper, we discuss our success in transforming aryl bromides into 1,4-disubstituted triazoles employing DMEDA as a ligand with a copper...
