Abstract

442 S. KAJIGAEs, T. KAKINAMI, M. MoRwAkı, T. TANAKA, S. FUJIsAkı, and T. OKAMOTO and the bromination of toluene gave a mixture of o-, p-bromo and dibromo derivatives. The reaction of 1 with equimolar amount of BTMA ICl3, and ZnCl3 at room temperature usually gave monoiodoarenes, and with 2-equiv of BTMA ICl, and ZnCl, at 70°C usually gave diiodoarenes. Thus, the objective mono-, or diiodoarenes could be obtained selectively ...
