treated with cyanomethyltriphenylphosphonium chloride oxadiazine-, and pyridazine derivatives were obtained whereas bis-indanylidene derivatives resulted from the reaction of 1 with methyl_ and ethyltriphenylphosphonium bromides. On the other hand, a series of substituted and unsubstituted spiro[3′]pyrazoles were obtained from the di azo substrate when reacted with vinyl_and allyltriphenylphosphonium
为了合成许多稠合和稠合的N-杂环,将不同类型的car碳负离子应用于2-重氮-1,3-二氧代-2,3-二氢-1 H-茚满-2-化物(1)。当用氰基甲基三苯基氯化chloride处理1时,得到了恶二嗪-和哒嗪衍生物,而双茚二烯衍生物是由1与甲基和乙基三苯基溴化bro的反应产生的。另一方面,当重氮化物与乙烯基和烯丙基三苯基溴化react反应时,从重氮基上获得了一系列取代的和未取代的螺[3']吡唑。
