Abstract: Abstract A cost-effective and expeditious one-pot synthesis of 1-(2-bromo-1-arylethyl)-1H-benzotriazoles has been devised by reacting styrene and their derivatives with 1H-benzotriazole in presence of N-bromosuccinimide in anhydrous CH2Cl2 at room temperature. Further, the resulted compounds undergo… read more here.

DOI: 10.1016/j.tetlet.2017.07.016
Abstract: Abstract Facile synthetic routes to bromo- and iodo-1,2,3-triazoles were achieved. Diiodo-1,2,3-triazole was directly obtained from 1,2,3-triazole, and dihalo-1,2,3-triazoles were converted to halo-1,2,3-triazoles in good yields without protection by NH. Unsymmetrical 4-bromo-5-iodo-1,2,3-triazole was synthesized from bromo-1,2,3-triazole.… read more here.
