Abstract

In this research project, a combination of poly (N, N'-dibromo-N-ethylene-benzene-1, 3- disulfonamide)[PBBS] and/or (N, N, N', N'-tetrabromobenzene-1, 3-disulfonamide)[TBBDA] with sodium nitrite in the presence of wet SiO2 (50% w/w) was used as an efficient nitrosating agent for the conversion of secondary amines to their corresponding nitroso compounds. N-Nitrosation reaction has been performed in dichloromethane at room ...
