Abstract

original image

The butterfly effect (a small change can have large repercussions): Dissociative electron attachment (DEA) was used to probe the reactivities of purine derivatives. A change of the substituent at the C6 position of adenine strongly affects the ion yield of the closed-shell dehydrogenated anion (see picture), although the hydrogen loss can be ascribed exclusively to the diametric N9 position.
