Laser-flash photolysis studies have been carried out on a solution of ap- and sp-9-(2-azido-4,6-dimethylphenyl)fluorenes (3) in methanol-ether at 25°C. The rates of formation of azanorcaradiene (5) from ap-nitrene (4) ap, and of 9-methoxyfluorene (7) from o-quinoid intermediate (6) were determined. The deuterium isotope effect on the migration of the hydrogen is discussed.
激光闪光光解研究已在25°C下在甲醇-醚溶液中对ap-和sp-9-(2-叠氮基4,6-二甲基苯基)芴(3)进行了研究。确定了由对-re-丁烯(4)ap形成的氮杂壬二烯(5)和由邻-醌型中间体(6)形成9-甲氧基芴的速率。讨论了氘同位素对氢迁移的影响。
