制备 des ap-et sp-([azido-2' dimethyl-4',6' phenyl]-9) fluorenes a partir des aminesrespondantes et制备 egalement des nitrenes相应的 qui presentent des comportements oppose a la fois dans leurs specters UV et RPE a 温度cryoogenique et dans leur reactive photochimique dans les fluides
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.
