L. Heinrich et al., Cobalt(III) complexes with carboxamido-N and sulfenato-S or sulfinato-S ligands suggest that a coordinated sulfenate-S is essential for the catalyticactivity of nitrile hydratases, EUR J INORG, (9), 2001, pp. 2203-2206
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.
