The new ligand N3PyamideSR and its FeII complex [FeII(N3PyamideSR)](BF4)2 (1) are described. Reaction of 1 with PhIO at -40 C gives metastable [Fe IV(O)(N3PyamideSR)]2+ (2), containing a sulfide ligand and a single amide H-bond donor in proximity to the terminal oxo group. Direct evidence for H-bonding is seen in a structural analogue, [Fe II(Cl)(N3PyamideSR)](BF4)2 (3). Complex 2 exhibits rapid O-atom transfer (OAT) toward external sulfide substrates, but no intramolecular OAT. However, direct S-oxygenation does occur in the reaction of 1 with mCPBA, yielding sulfoxide-ligated [Fe II(N3PyamideS(O)R)](BF4)2 (4). Catalytic OAT with 1 was also observed.

The non-heme iron complexes, [FeII(N3PySR)(CH 3CN)](BF4)2 (1) and [FeII(N3Py amideSR)](BF4)2 (2), afford rare examples of metastable Fe(iii)-OOH and Fe(iii)-OOtBu complexes containing equatorial thioether ligands and a single H-bond donor in the second coordination sphere. These peroxo complexes were characterized by a range of spectroscopic methods and density functional theory studies. The influence of a thioether ligand and of one H-bond donor on the stability and spectroscopic properties of these complexes was investigated. This journal is the Partner Organisations 2014.
