Thermal transformation of 7,8-diazabicyclo[4.2.2]deca-2,4,7,9-tetraene N-oxide (3) was observed, (Z)-benzaldehyde oxime being the major product, with (E)-benzaldehyde oxime as a minor product. N-Oxide 3 was labeled with deuterium α to the oxidized N-atom. The location of the deuterium label in the thermolysis products fitted one of two reasonable mechanisms.
观察到7,8-二氮杂双环[4.2.2] deca-2,4,7,9-四烯N-氧化物的热转化(3),(Z)-苯甲醛肟为主要产物,(E)-苯甲醛肟为次要产品。N-氧化物3用氘α标记到氧化的N原子上。氘标记在热解产物中的位置符合两种合理机制之一。
