Facile N-Nitrosation of Secondary Amines Using Poly(N,N'-dibromo-Nethylene- benzene-1,3-disulfonamide)and N,N,N',N'-tetrabromobenzene- 1,3-disulfonamide/NaNO<sub>2</sub> Under Mild Conditions
N‐Nitrosation of different types of secondaryamines has been proceeded usingsupportedperchloricacid on silicagel and sodiume nitrite under heterogeneous conditions. The operational system is simple and high pure products can be easily isolated with good to high yields.
An efficient and environmentally electrooxidative N-nitrosation of secondary amines using potassium/sodium nitrite as nitrosating agents has been developed. This strategy break through the innate combination of sodium nitrite and a strong acid. The reaction is compatible with the late-stage modification of pharmaceutical compounds and could be conducted in gram scale with high reaction efficiency.
