Abstract

TBAF-assisted N-arylation and benzylation of benzazoles such as 1 H-benzimidazole, 1 H- indole, and 1 H-benzotriazole with aryl and benzyl halides have been demonstrated under the ligand/base/solvent-free conditions. In the presence of CuBr2 and TBAF (n-Bu4NF), the azoles underwent N-arylation and benzylation with aryl and benzyl halides smoothly in moderate to good yields. It is noteworthy that the reaction is conducted under the ligand/ ...
