Surface Immobilized Cu-1,10-Phenanthroline Complexes with α-Aminophosphonate Groups in the 5-Position as Heterogenous Catalysts for Efficient Atom-Transfer Radical Cyclizations

Many Cu catalyzed ATRC reactions suffer from low catalyst activity and stability. We synthesize five 1,10-phenanthroline ligands substituted in the 5-position with α-aminophosphonate groups, through which the corresponding Cu complexes...
