Under these optimized conditions different N-heterocycle-substituted iodoarenes 3 were synthesized (Scheme 1 -a). The unsubstituted triazole 1b was isolated in 53% yield, whereas the N-bound triazole 1c could only be obtained in 13% yield. The benzimidazole 1d was smoothly synthesized in 60% yield, while the benzoxazole 1e gave a moderate yield of 21%.
