Abstract

Resin-bound organic ionic bases (RBOIBs) were developed in which tetraalkyl-ammonium or phosphonium cations are covalently attached to solid resins. The application tests showed that the performance of the tetraalkyl-ammonium-type RBOIBs is slightly better than that of the corresponding Cs salts in Cu-catalyzed C− N cross-couplings, while the tetraalkylphosphonium-type RBOIBs are significantly better than all the inorganic bases. ...
