Strong NH···S hydrogen bonds in molybdoenzyme models containing anilide moieties

Monooxomolybdenum(IV) and dioxomolybdenum(VI) benzenedithiolate derivatives containing anilide moieties were synthesized and characterized by (1)H NMR, UV-visible, IR, and Raman spectroscopies. These complexes exhibit very strong intramolecular NH···S hydrogen bonds formed by the acidic anilide NH p...

Zusammenfassung:Monooxomolybdenum(IV) and dioxomolybdenum(VI) benzenedithiolate derivatives containing anilide moieties were synthesized and characterized by (1)H NMR, UV-visible, IR, and Raman spectroscopies. These complexes exhibit very strong intramolecular NH···S hydrogen bonds formed by the acidic anilide NH proton and the desired coplanar structure, resulting in significantly positive redox potential and remarkable acceleration in the reduction of Me3NO in DMF.
