Thermal nitrogen extrusion of 2-methylene-6,7-diazabicyclo[3.2.2]non-6-enes and 6,7- diazabicyclo[3.2.2]nona-2,6-diene,6 proceeded easily to give closure and cleavage products via the corresponding 5-methylene-1,4-cycloheptylenes and 4-cyclohepten-1,3-ylenes, respectively.
2-亚甲基-6,7-二氮杂双环[3.2.2] non-6-烯和6,7-二氮杂双环[3.2.2] nona-2,6-二烯,6的热氮挤出很容易进行,从而产生闭合和断裂产物分别通过相应的5-亚甲基-1,4-亚环戊烯和4-环庚基-1,3-亚乙基得到。
