Iodine Mediated Nitrosation of Imidazo[1,5-A]n-heteroarenes Using TBN (tbuono) Reagent

An iodine mediated regio-selective nitrosation of imidazo[1,5-a]N-heteroarenes is reported using TBN as nitroso source. This method afford synthetically useful and medicinally interesting 3-nitroso imidazo[1,5-a]N-heteroarenes in moderate to good yields with good functional group tolerance. Further, this reaction could applicable on gram-scale level synthesis.
