Abstract: The solvolysis of l-chloro-3, 3-dimethyI-2-azabicyclo [2.2. 2] octane (2) was examined in 70% dioxane-water and in absolute ethanol. The sole products were 4-[2- amino-2-propyl] cyclohexanone (8) and l-ethoxy-3, 3-dimethyI-2-azabicy-clo [2.2. 2] octane (9). respectively. The first-order rate constants at 52O were (3.7 f 0.13) X sec-I, respectively. The corresponding carbon analogs, l-bromo-3, 3-dimethylbicyclo [2.2. 2] octane (6) and 1- ...
