Pyrazinecarbonitriles can be decyanated by hydrogenation with platinum on carbon in the presence of activated carbon under acidic conditions. Pyrazine carbonitrile-N-oxides undergo a stepwise reduction to the deoxy-pyrazinecarbonitriles followed by decyanation to give pyrazines in good yields. (C) 2002 Published by Elsevier Science Ltd.
