摘要：
It is known that the presence of a carbonyl group at C2 in norbornane compounds aids in the S(N)2 displacement of substituents at C7. In this study, we report a significant enhancement in reactivity at C7 by a second carbonyl group at C3. These diketones undergo rapid inversion at 80degreesC, while the monoketone does not exhibit any reactivity at this temperature. The increase in reactivity is attributed to electric field effects.
