  由甲基亚硝基酰胺形成重氮甲烷的速率。重氮甲烷溶液对碱水溶液的稳定性

  摘要：

  N-甲基-N-亚硝基酰胺被碱金属水溶液水解的速率变化很大。甲基亚硝基脲（1）在低温下被KOH水溶液迅速水解，得到高产率的重氮甲烷。在相似的条件下，N，N'-二甲基-N，N'-二亚硝基-乙酰胺（3）的水解更缓慢，但重氮甲烷的收率也很高。N，N'-二甲基-N，N'-二亚硝基对苯二甲酰胺（4）和（N-甲基-N-亚硝基）-4-氨基-4-甲基-2-戊酮（5）不易被水溶液水解KOH解决方案。ñ-甲基-N-亚硝基-对甲苯磺酰胺（2）在所测试的化合物中反应性最低。重氮甲烷在甲苯中与含水碱的水解遵循一级动力学。水解速度受碱的浓度和强度以及温度的影响很大。

• The thermal deazetations of fluorinated 2,3-diazabicyclo[3.2.0]hept-2-enes
  作者：William R. Dolbier、Dheya M. Al-Fekri

  DOI：10.1016/s0040-4020(01)89928-2

  日期：1987.1

  Thermal deazetation of difluoro- and tetrafluoro-2,3-diazabicyclo[3.2.0]hept-2-enes proceed via two parallel mechanistic pathways, one involving formation of a diradical via simple N2 loss, and the other proceeding via a retro-dipolar cycloaddition process. A key finding was the absence of isolation of a bicyclopentane product in the difluoro case.
