Thermal cheletropy in model azabicycles; the question of linear vs. non-linear extrusion
Abstract
Comparison between N-nitroso-9-azabicyclo-[4,2,1]nona-2,4,7-triene (1b), N-nitroso-9-azabicyclo-[4,2,1]nona-2,4-diene (2b) and N-nitroso-9-azabicyclo-[4,2,1]non-7-ene (3b) in terms of their tendency to undergo bridge extrusion under the influence of basic hydrosulphite, reveals distinct preference for ‘linear’ cheletropy.
