Organic electrochemistry

Organic electrosynthesis agrees well with the principles of green chemistry [1] as it is possible to electrochemically regenerate the catalyst by applying a certain potential. For example for an oxidation reaction, no stoichiometric oxidant has to be added and a stream of toxic waste is avoided. There is a continuous search for attractive catalysts/mediators which are able to selectively oxidize the target molecules at low overpotential. Synthetic applications with ruthenium catalysts are currently under investigation in our laboratory.

Cyclic voltammograms of 1 mM ruthenium catalyst in 0.1 M Bu4NBF4 acetonitrile solution at Pt electrode with different scan rates ( 50 mVs-1; 75 mVs-1; 100 mVs-1; 150 mVs-1; 250 mVs-1; 500 mVs-1). The figure shows different cylic voltammograms of a ruthenium catalyst, the influence of the scan rate is here examined on the oxidation/reduction couple.
