Those N-alkynyl heteroaromatic iodoarenes reveal the possibility for further functionalization, either through the iodine or alkyne. The latter was demonstrated in a click-reaction of the triazole 14 with TMS-N 3 , yielding the bi-triazole 15 in 61% yield (Scheme 3 -e). To the best of our knowledge this is the first direct C-N connection of two triazoles described so far.
