Abstract A number of reactions for evoking skeletal rearrangement in 1-(cyclohex-1′-enyl)-1-nitro-2-substituted phenyl ethenes (1–2) and 1-(3-bromo-cyclohex-1′-enyl)-1-nitro-2-substituted phenyl ethenes (6–7), the model compounds representing 2-nitro-1,3-diene system have been studied for obtaining derivatives of 1-nitro-1,3-dienes. Of these, the reaction of compound 6 with tributyl tin hydride (TBTH)
摘要 1-(环己-1'-烯基)-1-硝基-2-取代的苯基乙烯(1-2)和1-(3-溴-环己-1'-烯基)中引起骨架重排的许多反应-1-硝基-2-取代的苯基乙烯(6-7),代表2-硝基-1,3-二烯系统的模型化合物已经被研究用于获得1-硝基-1,3-二烯的衍生物。其中,发现化合物 6 与氢化三丁基锡 (TBTH) 的反应最适合引发所需的骨架重排。化合物 1、2、6、7 与叠氮化钠的反应导致硝基的消除,并导致形成 4,5-二取代的 1H-1,2,3-三唑。±CDRI 通讯编号 5482
