cycloalkanones, 1-(2-oxocycloalkyl)ethane-1,1,2,2-tetracarbonitriles, reacted with aqueous ammonia at room temperature to give, depending on the cycloalkane ring size and reaction conditions, three types of nitrogen-containing heterocyclic compounds. The reaction of tetracyanoethylene-cyclohexanone adducts with 20–25% aqueous ammonia afforded 10,11-diazatricyclo[5.3.2.01,6]-dodec-8-ene derivatives, whereas
环烷酮,1-(2-氧代环烷基)乙烷-1,1,2,2-四甲腈的四乙氨基乙烯加合物在室温下与氨水反应,根据环烷烃环的大小和反应条件,得到三种类型的含氮化合物杂环化合物。四氰基乙烯-环己酮加合物与20-25%的氨水反应得到10,11-二氮杂三环[5.3.2.0 1,6 ] -dodec-8-ene衍生物,而它们的七元和八元类似物被转化为吡咯并[在相似条件下的3,4- c ]-吡啶。用10-15%的氨水处理1-(2-氧代环辛基)乙烷-1,1,2,2-四甲腈导致形成2,5-二氨基-3-(2-氧代环辛基)-3 H-吡咯-3,4-二碳腈为两种非对映异构体的混合物。
