Investigations on the Synthesis, Structural Characterization, and Crystal Structures of Three Diiron and Tetrairon Azadithiolate Complexes

Abstract

Three diiron and tetrairon azadithiolate complexes as models for the active site of [FeFe] hydrogenase were prepared. Reaction of complex Fe 2 (SCH 2 OH) 2 (CO) 6 and NH 2 CH 2 CH 2 CH 2 OCH 3 resulted in the diiron azadithiolate hexcarbonyl complex Fe 2 [(SCH 2 ) 2 -NCH 2 CH 2 CH 2 OCH 3 ](CO) 6 (1) in moderate yield. Furthermore, treatment of complex 1 with mono phosphine ligand PPh

“…Triphenylphosphane (23 mg, 87 μmol) was added to the brown solution and the reaction mixture was stirred for another hour. The solvent was removed under reduced pressure and the crude product was purified by column chromatography ( n ‐hexane/DCM 1 : 2) to get 5 as a brown, oxygen sensitive solid (41 mg, 51 μmol, 59 %) [24] …”
