The reaction products of nitrous acid on 5-amino-3, 4-dialkylisoxazoles (Ia, b, c) has been formulated as 4-(3, 4-dialkyl-5-isoxazolyl)azo-3, 4-dialkyl-5(4H)-isoxazolones (IVa, b, c) rather than the azoxy structure (II) which was originally proposed by Hanriot. To gain insight into this reaction mechanism, the behavior of o-, m-, and p-nitrobenzenediazonium chlorides on Ia has been also investigated.
亚硝酸在 5-氨基-3, 4-二烷基异恶唑 (Ia, b, c) 上的反应产物已公式化为 4-(3, 4-二烷基-5-异恶唑基)偶氮-3, 4-二烷基-5( 4H)-异恶唑酮(IVa,b,c)而不是最初由Hanriot提出的氧化偶氮结构(II)。为了深入了解该反应机理,还研究了邻硝基氯化重氮、间硝基氯化和对硝基氯化重氮在 Ia 上的行为。
