Visible Light-Induced Oxidized Carbon Nitride Catalysis toward Regioselective Ring Opening of Aziridines

An efficient and green, oxidized carbon nitride-catalyzed, visible-light-driven regioselective ring opening of tosylaziridines from a variety of nucleophiles (OR, Br, N₃) is reported. The developed methodology is also applied to epoxides, affording a library of 2-substituted amines-/alcohols in excellent yields (86-95%). Advantages of the developed methodology include regioselectivity, operational simplicity, ambient reaction conditions, and the recyclability of the heterogeneous catalyst up to five times without any substantial change in its morphology and catalytic efficiency.
