Abstract
A bis(sulfenato-S)Co-III complex and its corresponding bis(sulfinato-S) com plex were prepared. Their catalytic nitrile hydration activity was tested. Whereas the former catalyzes the hydration of CH3CN under mild acidic condi tions, the latter is inactive. A mechanism for this reaction is proposed, i n relation with nitrile hydratase activity.
