Facile N-Nitrosation of Secondary Amines Using Poly(N,N&#39;-dibromo-Nethylene- benzene-1,3-disulfonamide)and N,N,N&#39;,N&#39;-tetrabromobenzene- 1,3-disulfonamide/NaNO<sub>2</sub> Under Mild Conditions
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 temperature under mild and heterogeneous
conditions. The reaction is operationally simple and corresponding products were achieved in good to excellent
yields.

N-Nitrosodialkylamines underwent photolysis in the presence of an acid. From the analysis of the end products, the primary photolysis products were shown to be [NOH] and the corresponding alkylideneimine, which underwent further reaction, e.g. (i) recombination of the two species to give amidoximes, (ii) hyponitrous acid formation, and (iii) hydrolysis or polymerization. A pathway is proposed for the

Neat chlorosulfonic acid reacts with silicagel to give silica sulfuric acid in which sulfuric acid is immobilized on the surface of silicagel via a covalent bond. A combination of silica sulfuric acid and sodium nitritein the presence of wet SiO 2 was used as an effective nitrosating agent for the nitrosation of secondaryamines to their corresponding nitroso derivatives under mild and heterogeneous
