Eosin Y catalyzed visible light oxidative C-C and C-P bond formation

Abstract

Eosin Y catalyzes efficiently the visible light mediated coupling of sp(3) 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.
