Twenty azobenzene derivatives structurally related to 3'-hydroxymethyl-4-(dimethylamino) azobenzene (3'-CH2OH-DAB) were synthesized for the purpose of investigating their mutagenic and carcinogenic effects. They are oxidation products of 3'-Me-DAB, symmetrically substituted azo compounds, their acetyl or chloro derivatives, and their isomers. The 4-(dimethylamino) azobenzenes were prepared by coupling of the corresponding diazonium salts with N, N-dimethylaniline and the azobenzenes by reduction of the corresponding nitrobenzenes with lithium aluminum hydride or zinc in a sodium hydroxide medium. Physical characteristics of these compounds (melting point, elemental analysis, and infrared, ultraviolet, and mass spectral data) are given.
合成了与3'-羟甲基-4-(二甲氨基)偶氮苯结构相关的20种偶氮苯衍生物,旨在研究其诱变和致癌效应。它们是3'-甲基-DAB的氧化产物、对称取代的偶氮化合物、它们的乙酰或氯衍生物及其异构体。4-(二甲氨基)偶氮苯是通过相应的重氮盐与N,N-二甲基苯胺反应制备的,而偶氮苯则通过相应的硝基苯在氢氧化钠介质中用氢化铝锂或锌还原得到。给出了这些化合物的物理特性(熔点、元素分析、红外、紫外和质谱数据)。
