Greener, facile and ultrasound assisted synthesis of 1,2,3-triazole via CuAAC of 2-(azidomethyl)-1H-benzo[d]imidazole and alkynes and their evaluation of antimicrobial activity

An expeditious room temperature protocol for the synthesis of 1,4-disubstituted 1H-1,2,3-triazol-1-yl)methyl)-1H-benzo[d]imidazole from [3+2] cyclization by using 1H-benzo[d]imidazole azide and various substituted terminal alkynes and copper(I) as a catalyst. This synthetic approach has been various prominent features such as fewer reaction steps, Good Yield, simple reaction condition and no any further purification required. Characterizations of all the synthesized compounds were done by various spectroscopic techniques like FT-IR, NMR and Mass spectrometry. All the synthesized targeted compounds were screened and evaluated for their antimicrobial activities.
