mixture of nitric and sulphuric acids or nitric acid with conversion of the side chain. In the reactions with mixtures of HNO3 and H2SO4, the formation of N-nitroso-N-methyl and N-nitro-N-methylpentafluoroanilines is observed. The ratio of these products was found to depend on the ratio of the acids: the formation of N-nitro-N-methylpentafluoroaniline increases with the quantity of sulphuric acid; N-ni
N,N-二甲基五氟苯胺容易与硝酸和硫酸或硝酸的混合物发生反应,并带有侧链转化。在与HNO 3和H 2 SO 4的混合物的反应中,观察到N-亚硝基-N-甲基和N-硝基-N-甲基五氟苯胺的形成。发现这些产物的比例取决于酸的比例:N-硝基-N-甲基五氟苯胺的形成随硫酸的量而增加;N-亚硝基当仅使用硝酸时,获得-甲基五氟苯胺。Ñ,Ñ -Dimethylperfluoro- p -甲苯胺,Ñ,Ñ -dimethylperfluoro -2,4-二甲代苯胺,Ñ,Ñ -dimethylperfluoro -5-氨基茚满经历类似的变换。Ñ亚硝基衍生物通过HNO的混合物转化3和H 2 SO 4,HNO 3或NO 2 BF 4成相应Ñ硝基衍生物。形成相应的N-亚硝基-N时,会发生甲基衍生物Ñ,Ñ -dimethylpentafluoroaniline,Ñ,Ñ -dimethylperfluoro- p -甲苯胺与HNO处理2。
