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

during the repetitive use of these catalyst systems. Therefore, catalytic systems without ligands are of special interest. Cu(I)catalyzed C-Ncross-couplingreaction was reported using organic anion bases, such as quaternary ammonium hydroxide, which can contribute to form a homogeneous catalytic system. In present work, we report that C-N coupling reaction of aryl iodides and bromides with alkyl amines
