Radical thiol additions to 7-azanorbornadienes give 7-thio-substituted 2-azanorbornenes and Barton deoxygenations of 7-azabenzonorbornanols give 2-azabenzonorbornanes. The processes both involve novel nitrogen-directed radical rearrangements. The kinetics and mechanisms of the reactions are also discussed.
向7-氮杂降冰片二烯中自由基硫醇的加成得到7-硫基取代的2-氮杂降冰片烯,并且7-氮杂苯并降冰片醇的巴顿脱氧得到2-氮杂苯并降冰片烷。这两个过程都涉及新颖的氮导向的自由基重排。还讨论了反应的动力学和机理。
