Abstract

The stable 2,2-diphenyl-1,2-dihydroquinolinenitroxide radicals 1 react with nitric oxide (NO) to form the stable nitro compounds 2 and 3 as main products. The stable dinitro compounds 6 and 1,2-dihydroquinolines 7 are formed in minor yield as side-products accom­panied with the unstable N-nitroso compounds 4 and 5, which further decompose to form the stable products mentioned above. The proposed mechanism of the reaction is discussed in terms of homolytical processes and is supported by PM 3 calculations.
