EosinY catalyzes efficiently the visible light mediated coupling of sp3 C–H bonds adjacent to the nitrogen atom in tetrahydroisoquinoline derivatives in the absence of an external oxidant. Nitroalkanes, dialkyl malonates, malononitrile, and dialkyl phophonates were used as pronucleophiles in this metal-free, visible light oxidative coupling reaction.

Direct oxidation coupling of tertiary amines and dialkyl- or diphenyl-substituted phosphonates was developed. The reaction was mediated by DDQ under roomtemperature. Various phosphonates and N-aryl tetrahydroisoquinolines were tolerated in this reaction, and α-aminophosphonates were obtained with up to 99% yield.
