Electrochemically Controlled Proton-Transfer-Catalyzed Reactions at Liquid-Liquid Interfaces: Nucleophilic Substitution on Ferrocene Methanol

Electrochemically controlled proton-transfer-catalyzed reactions at liquid-liquid interfaces: nucleophilic substitution on ferrocene methanol.

The generation of α-ferrocenyl carbocations from ferrocenyl alcohols for S(N)1 substitution at the water-organic solvent interface is initiated by the transfer of protons into the organic phase. The proton flux, and hence the reaction rate, can be controlled by addition of a suitable "phase-transfer catalyst" anion or by external polarization with a potentiostat, providing a new method for the ...

Proton-coupled oxygen reduction at liquid-liquid interfaces catalyzed by cobalt porphine.

Cobalt porphine (CoP) dissolved in the organic phase of a biphasic system is used to catalyze O(2) reduction by an electron donor, ferrocene (Fc). Using voltammetry at the interface between two immiscible electrolyte solutions (ITIES), it is possible to drive this catalytic reduction at the interface as a function of the applied potential difference, where aqueous protons and organic electron d...

Fast ion-transfer processes at nanoscopic liquid/liquid interfaces.

Ion-transfer (IT) reactions at a liquid/liquid (L/L) interface or at an interface between two immiscible electrolyte solutions (ITIES) are of great fundamental interest because they play a key role in many important physicochemical and biological systems, such as in phase-transfer catalysis, sensors, drug delivery, and biological membranes. The kinetics of IT reactions at such interfaces has be...
