Webb28 feb. 2024 · Cyclic iron tetracarbenes are an emerging class of macrocyclic iron N-heterocyclic carbene (NHC) complexes. They can be considered as an organometallic compound class inspired by their heme analogs, however, their electronic properties differ, e.g. due to the very strong σ-donation of the four combined NHCs in equatorial … Webb21 aug. 2024 · The reaction between persulfate ions (peroxodisulfate ions), S 2 O 82-, and iodide ions in solution can be catalyzed using either iron (II) or iron (III) ions. The overall equation for the reaction is: (2) S 2 O 8 2 − + 2 I − → 2 S O 4 2 − + I 2. For the sake of argument, we'll take the catalyst to be iron (II) ions.
