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.
在本研究项目中,利用聚(N,N'-二溴-N-亚乙基-苯-1,3-二磺酰胺)[PBBS]和/或(N,N,N',N'-四溴苯-1,3-二磺酰胺)[TBBDA]与亚硝酸钠在含湿二氧化硅(50% 质量/质量)的存在下,作为高效的次硝基化剂,将二级胺转化为相应的亚硝基化合物。N-亚硝化反应在室温下,在二氯甲烷中于温和且异质条件下进行。该反应操作简便,其产物产率良好至优秀。
