Graphical Abstract

Wasser funkt dazwischen: Hydratisierte I(CH3I)-Komplexe, I(CH3I)(H2O)1–3, wurden durch IR-Photodissoziationsspektroskopie untersucht, um die Zwischenstufen der SN2-Reaktion I+ CH3I → ICH3+ I unter hydratisierten Bedingungen zu identifizieren. Aus den Strukturen und Energetiken der Komplexe kann gefolgert werden, dass ein oder zwei H2O-Moleküle genügen, um diese SN2-Reaktion wirksam zu unterdrücken.
