Highly efficient iron(II) chloride/N-bromosuccinimide-mediated synthesis of imides and acylsulfonamides
We have developed a general and highly efficient iron(II) chloride/N-bromosuccinimide (NBS)-mediated method for the synthesis of imides and acylsulfonamides via couplings of thioesters with carboxamides/sulfonamides, and the method is simple, economical and shows practical advantages.
