(E)-3-p-Anisyl-2-cyano-2-propenoyl chloride and/or azide (1b and c) underwent successful nucleophilic displacement reactions, with urea and thiourea derivatives to give the mono- or di- displacement products (4, 8, 2 and 5) respectively, beside other cyclic products (3 and 6); with aromatic binucleophilies e.g. o-phenylene diamine, the expected di-displacement products (12 and 13) were obtained while with 2-aminophenol a mixture of two mono-displacement products (15 and 16) were isolated.
(E)-3-安息香基团-O-亚硝基-2-丙二烯酰基-1,2-二氯乙二烯酸氯化物和亚硝基氯化物(1b和c)在亲核取代反应中表现良好,分别与尿酸和硫尿酸衍生物结合,生成了单取代或双取代产物(4、8、2和5),此外还生成了外加其他环状产物(3和6)。使用如o-苯氧基二胺这样的二取代试剂,预期生成了双取代产物12和13,而使用2-氨基苯酚则生成了两种单取代产物的混合物15和16。
