Inhibition of Copper Corrosion with N-Arylaminotriazoles in Aqueous Chloride Solutions and in Air

Visible Light-Enhanced [3 + 2] Cycloaddition of N,N-Disubstituted Hydrazines with Organo-Cyanamides: Access to Polysubstituted 1,2,4-Triazol-3-amines

“…Recently, photocatalysis has proven to be a powerful tool for the synthesis of various valuable organic molecules because of clean, pollution-free, renewable energy, and resource-rich, which meets the demands of green synthetic chemistry . Organic hydrazines are one of the significant starting materials for the construction of various nitrogen-containing compounds. , Inspired by previous reports, we herein report an efficient visible light-enhanced [3 + 2] cycloaddition of N , N -disubstituted hydrazines with NCTS to various polysubstituted 1,2,4-triazol-3-amines (Scheme f), which are privileged structures in many bioactive molecules and functional materials . The reaction involves a C­(sp 3 )–H activation and cyano addition/cyclization cascade process.…”
