Nitrogenase Model Complexes [Cp*Fe(mu-SR1)(2)(mu-eta(2)-(RN)-N-2=NH)FeCp*] (R-1 = Me, Et; R-2 = Me, Ph; Cp* = eta(5)-C5Me5): Synthesis, Structure, and Catalytic N-N Bond Cleavage of Hydrazines on Diiron Centers
The reactions of [Cp*Fe(mu-SR1)(3)FeCp*] (Cp* = eta(5)-C5Me5; R-1 = Et, Me) with 1.5 equiv (RNHNH2)-N-2 (R-2 = Ph, Me) give the mu-eta(2)-diazene diiron thiolate-bridged complexes [Cp*Fe(mu-SR1)(2)(mu-eta(2)-(RN)-N-2 NH)FeCp*], along with the formation of PhNH2 and NH3. These mu-eta(2)-diazene diiron thiolate-bridged complexes exhibit excellent catalytic N-N bond cleavage of hydrazines under ambient conditions.
