Oxygenation of thiolates to S-bonded sulfinate in an iron III complex related to nitrile hydratase.

Erwan Galardon1, Michel Giorgi, Isabelle Artaud.   

Abstract

Air oxidation of the iron(III) complex derived from (2-mercaptoisobutyryl)-4,5-dichloro-O-phenylenediamine in the presence of Et4NCN afforded the corresponding disulfinato species. With two carboxamido nitrogens trans to two S-bonded sulfinates, this complex mimics the disulfinate inactive form of Fe-NHase.
