4,N,N-Trimethyl-3-nitrobenzenamine gave reductive denitration products (ca. 28%) upon treatment with n-butyl nitrite in the presence of catalytic amounts of ammonium chloride and water in an unprecedented one-reagent single-pot process. The three isomeric N,N-dimethylnitrobenzenamines showed the same behaviour to a much lesser extent; the ortho isomer was partially (7%) transformed into 1-methylbenzotriazole. Keywords: aromatic protolytic denitration, nitroaromatics, n-butyl nitrite, E- and Z-nitrosamine.
4,N,N-三甲基-3-硝基苯胺在氯化铵和水存在下,与正丁硝酸酯处理后产生还原脱硝产物(约28%)在一个前所未有的单试剂单锅过程中。三种同分异构的N,N-二甲基硝基苯胺以较小程度显示相同行为;邻位异构体部分(7%)转化为1-甲基苯并三唑。关键词:芳香质子化脱硝,硝基芳烃,正丁硝酸酯,E-和Z-亚硝胺。
