A series of benzothiazole and benzoxazole linked 1,4-disubstituted 1,2,3-triazoles was synthesized through copper(I) catalyzed azide-alkyne cycloaddition reaction. FTIR, 1H, 13C-NMR and HRMS techniques were used to examine the structure of synthesized derivatives. Further, these triazole derivatives were screened for in vitro antibacterial activities against two Gram-positive bacteria S. aureus, B. subtilis; two Gram-negative bacteria E. coli and K. pneumoniae by serial dilution technique, reflecting moderate to good activity. Compound 7s exhibited promising antibacterial activity among all the synthesized triazoles
