Protonation Studies of the New Iron Carbonyl Cyanide
trans-[Fe(CO)3(CN)2]2-: Implications with Respect to Hydrogenases
Posted on 2003-07-31 - 00:00
The new iron carbonyl cyanide trans-[Fe(CN)2(CO)3]2-, [2]2-, forms
in high yield via photosubstitution of Fe(CO)5 with 2 equiv of
Et4NCN. Protonation of [2]2- generated [HFe(CN)2(CO)3]-, [2H]-,
the first H−Fe−CN−CO species. Further protonation gives dihydrogen. This simple system provides insights into hydrogen
evolution by the hydrogenase enzymes, which also feature H−Fe−CN−CO centers.
