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 deg 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.
