Dalton Transactions
Molecular transition metal phosphides (TMPs) containing a Rh₂P₂ and unprecedented Rh₄P₄ core could be generated from Na[OCP] and rhodium(i) precursor complexes carrying the bischelating tropPPh₂ ligand. These reaction proceed through a formal P-transfer step (trop = 5H-dibenzo[a,d]cyclohepten-5-yl), which involves migration of the CO unit to the Rh(i) center. With the related tetradentate ligand trop₃P and tridentate ligand trop₂PPh the first neutral and anionic [Rh_x(L)_n(PCO)_y]_z complexes containing up to two rhodium centers and three intact phosphaethynolate units. These complexes are inert against CO migration. The results demonstrate a large influence of the metal coordination sphere on product formation, and indicate that low-coordinate rhodium(i) precursors are most effective for the preparation of RhP complexes using Na[OCP] as P-source.
Ferryl for real. The Fenton reaction near neutral pH
Koppenol, Willem H. (2022)
Dalton Transactions
According to the literature, the Fenton reaction yields HO˙ and proceeds with 53 M⁻¹ s⁻¹ at 25 °C and low pH. Above pH 5, the reaction becomes first-order in HO⁻, and oxygen atom transfer has been detected, which indicates formation of oxidoiron(2+), FeO²⁺. These observations, and the assumption that the intermediate [FeHOO]⁺ decays approximately iso-energetically to FeO²⁺, allow one to estimate an Gibbs energy of formation FeO²⁺ of +15 ± 10 kJ mol⁻¹, from which follows the one-electron E°′(FeO²⁺, H₂O/[Fe(HO)₂]⁺) = +2.5 ± 0.1 V and the two-electron E°′(FeO²⁺, 2H⁺/Fe²⁺, H₂O) = +1.36 ± 0.05 V, both at pH 7. In the presence of HCO₃⁻, formation of FeCO₃(aq) occurs which may facilitate formation of the [FeHOO]⁺ intermediate, and leads to CO₃˙⁻. At pH 7, the product of the Fenton reaction is thus FeO²⁺, or CO₃˙⁻ if HCO₃⁻ is present.
