摘要：
(Chemical Equation Presented) Lost control: The rationalization of the ambident reactivity of NO2- by the change between charge control to orbital control has to be revised. SN1-type reactions of carbocations with NO2- give kinetically controlled product mixtures only when these reactions proceed without activation energy (diffusion control). Activation-controlled SN1 alkylations are reversible and lead to the thermodynamically more stable nitro compounds. © 2005 Wiley-VCH Verlag GmbH &Co. KGaA.
