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.

A comparison has been made of five methods for terminating the reaction of active nitrogen with ethylene in the temperature range 295° to 673° K. These were based on deactivating the active nitrogen by low-temperature trapping, by addition of nitric oxide, and by passing it over copper oxide or cobalt catalysts. With the nitric oxide and cobalt catalyst techniques, which appeared to be the most reliable of those used, an activation energy of 400 ± 200 cal/mole, with a P factor of about 10−5, have been determined for the reaction.


1. Effect of Catalysts in Promoting the Formation of Active Nitrogen . There has been considerable controversy on the question of whether or not pure nitrogen would give the afterglow, which, as I have shown in the previous papers of this series, is associated with the presence of chemically active nitrogen. E. P Lewis was disposed to think that the presence of oxygen or nitric oxide was essential, but in a much later paper, though still inclined to the same opinion, he states that the afterglow continually increased in intensity as the proportion of oxygen was reduced.
