The regioselective N2-substitution of 4-bromo-5-iodo-1,2,3-triazole with alkyl/aryl halides in the presence of KOin DMF produced the desired 2-substituted 4-bromo-5-iodo-1,2,3-triazoles as a major products in good to excellent regioselectivity. Subsequent chemoselective Suzuki-Miyaura cross-coupling reaction of N2-substituted 4-bromo-5-iodo-1,2,3-triazoles provided polysubstituted 1,2,3-triazoles efficiently.

"Chemical Equation Presented" Reaction of 4-bromo-NH-1,2,3- triazoles 2 with alkyl halides In the presence of K2CO3 in DMF produced the corresponding 2-substituted 4-bromo1,2,3-triazoles 5 In a regioselective process. Subsequent Suzuki cross-coupling reaction of these bromides provided an efficient synthesis of 2,4,5-trisubstituted triazoles 3. In addition, reduction of the bromotriazoles by hydrogenation furnished an efficient synthesis of 2,4-disubstituted triazoles 8.
