Iodobenzene → 1-Phenyl-1H-1,2,3-triazole

Participants

Reaction Steps

Following General Procedure A (90° C., 30 hours), 1H-[1,2,3]triazole (87 μL, 1.5 mmol) is coupled with iodo-benzene (112 μL, 1.0 mmol). The crude brown oil was purified by flash chromatography on silica gel (eluent: dichloromethane/hexanes=50/50 then pure dichloro-methane) to provide 60 mg of 2-phenyl-2H-[1,2,3]triazole (41% yield) as an uncolored oil and 70 mg of 1-phenyl-1H-[1,2,3]triazole (48% isolated yield) as a light yellow solid.
