There is disclosed a process for performing an isolated Pd(II) mediated oxidation reaction electrochemically. The inventive process is performed on an electrode array device having a plurality of separately addressable electrodes. Preferably, the Pd(II) mediated oxidation is a Wacker reaction. Specifically, there is disclosed a process for conducting an isolated Pd(II) mediated oxidation on a plurality of electrodes, comprising providing an electrode array device having a plurality of electrodes with a conductive electrode surface and a matrix or coating material over the electrodes surfaces; providing a solution bathing the electrode array matrix or coating material and electrode surfaces, wherein the solution comprises a transition metal species and a confining agent; and biasing one or a plurality of electrodes ('selected electrode or electrodes') with a voltage or current to regenerate the transition metal species required for the isolated Pd(II) mediated oxidation, whereby the confining agent limits diffusion of the transition metal species to a volume surrounding each selected electrode surface.
