Synthetic Models for the Active Site of the [FeFe]-Hydrogenase: Catalytic Proton Reduction and the Structure of the Doubly Protonated Intermediate

This report compares biomimetic hydrogen evolution reaction catalysts with and without the amine cofactor (adtNH): Fe2(adtNH)(CO)2(dppv)2 (1 NH ) and Fe2(pdt)(CO)2(dppv)2 (2) [(adtNH)2– = HN(CH2S)2 2–, pdt2– = 1,3-(CH2)3S2 2–, and dppv = cis-C2H2(PPh2)2]. These compounds are spectroscopically, struc...
