A reaction of cyclopropanediazonium ion, generated by decomposition of N-cyclopropyl-N-nitrosourea upon treatment with potassium or cesium carbonates, with various poly-hydroxyarenes and aminophenols has been studied. The reaction of azo-coupling proceeds with phloroglucinol, resorcinol, 3-methoxy- and 3-aminophenol giving rise to mono-, bis-, and tris(cyclopropylazo)arenes as the major products. Oxidizable phenols such as hydro-quinone, 2-methoxy-, 4-amino-, and 2-aminophenol give products of radical transformations with participation of cyclopropyl radical.
研究了环丙基重氮盐离子(由N-环丙基-N-亚硝基脲在钾或铯碳酸盐处理下分解生成)与各种多羟基芳烃和氨基苯酚的反应。偶氮偶联反应与间苯三酚、间苯二酚、3-甲氧基和3-氨基苯酚进行,生成单、双和三(环丙基偶氮)芳烃作为主要产物。可氧化的苯酚如对苯二酚、2-甲氧基、4-氨基和2-氨基苯酚会与环丙基自由基发生自由基转化反应。
