Abstract:
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.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
