Abstract An efficient synthesis of 1,5-diaryl-4-benzothiazolyl-substituted 1,2,3-triazoles by organocatalytic 1,3-dipolar cycloaddition reactions, from easily available benzo[d]thiazole derivatives and substituted azidobenzenes, has been developed. The 1,8-diazabicyclo[5,4,0]undec-7-ene is used as organocatalyst, and the 2-(1,5-diaryl-1H-1,2,3-triazol-4-yl)benzo[d]thiazoles were obtained in good yields
