is slightly better than that of the corresponding Cs salts in Cu-catalyzed C−Ncross-couplings, while the tetraalkylphosphonium-type RBOIBs are significantly better than all the inorganic bases. With these newly developed RBOIBs, room-temperature Cu-catalyzed C−N coupling with various nonactivated aryliodides and even aryl bromides can be readily accomplished. Moreover, RBOIBs can be easily recycled

We report the first examples of radical cation Smiles rearrangements. A series of aryloxy alkylamines underwent spontaneous reaction, with the amino group displacing the ipso-alkoxy group through substitution, at ambient temperature and under photoactivation by visible light in the presence of an acridinium catalyst (5 mol%). The study was extended to 3-(2-methoxyphenyl)propan-1-amine derivatives,
