Abstract

„Seifenblasen“: Protonen werden an einer weichen Grenzfläche zwischen Wasser und 1,2-Dichlorethan (DCE) unter Wasserstoffentwicklung durch [(C5Me5)2Fe] reduziert. Dabei folgt auf einen durch [(C5Me5)2Fe] unterstützten Protonentransfer durch die Grenzfläche die Reduktion der Protonen in DCE. Die Grenzfläche dient vorrangig als Protonenpumpe, mit deren Hilfe bei der Wasserstoffentwicklung direkt auf die wässrigen Protonen zugegriffen werden kann.
