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.

such as nitroalkanes, malononitrile, dimethyl malonate and H-phosphonate diesters were achieved by using a magnetic nanoparticle-supported eosin Y bis-benzyltriethylammonium salt (MNPs-Eosin Y) as catalyst and air as the sole oxidant, affording the corresponding products in good to excellent yields undermild reaction conditions. Notably, the supported eosin Y catalyst can easily be separated from the
