Abstract
Computational chemistry provides a versatile toolbox for studying mechanistic details of catalytic reactions and holds promise to deliver practical strategies to enable the rational in silico catalyst design. The versatile reactivity and nontrivial electronic structure effects, common for systems based on 3d transition metals, introduce additional complexity that may represent a particular challenge to the standard computational strategies. In this review, we discuss the challenges and capabilities of modern electronic structure methods for studying the reaction mechanisms promoted by 3d transition metal molecular catalysts. Particular focus will be placed on the ways of addressing the multiconfigurational problem in electronic structure calculations and the role of expert bias in the practical utilization of the available methods. The development of density functionals designed to address transition metals is also discussed. Special emphasis is placed on the methods that account for solvation effects and the multicomponent nature of practical catalytic systems. This is followed by an overview of recent computational studies addressing the mechanistic complexity of catalytic processes by molecular catalysts based on 3d metals. Cases that involve noninnocent ligands, multicomponent reaction systems, metal-ligand and metal-metal cooperativity, as well as modeling complex catalytic systems such as metal-organic frameworks are presented. Conventionally, computational studies on catalytic mechanisms are heavily dependent on the chemical intuition and expert input of the researcher. Recent developments in advanced automated methods for reaction path analysis hold promise for eliminating such human-bias from computational catalysis studies. A brief overview of these approaches is presented in the final section of the review. The paper is closed with general concluding remarks.

Abstract
![]()
The
oxidation of the C–H and C=C bonds of hydrocarbons with
H2O2 catalyzed by non-heme iron complexes with
pentadentate ligands is widely accepted as involving a reactive FeIV=O species such as [(N4Py)FeIV=O]2+ formed by homolytic cleavage of the O–O bond of an
FeIII–OOH intermediate (where N4Py is 1,1-bis(pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)methanamine).
We show here that at low H2O2 concentrations
the FeIV=O species formed is detectable in methanol.
Furthermore, we show that the decomposition of H2O2 to water and O2 is an important competing pathway
that limits efficiency in the terminal oxidant and indeed dominates
reactivity except where only sub-/near-stoichiometric amounts of H2O2 are present. Although independently prepared
[(N4Py)FeIV=O]2+ oxidizes stoichiometric
H2O2 rapidly, the rate of formation of FeIV=O from the FeIII–OOH intermediate
is too low to account for the rate of H2O2 decomposition
observed under catalytic conditions. Indeed, with excess H2O2, disproportionation to O2 and H2O is due to reaction with the FeIII–OOH intermediate
and thereby prevents formation of the FeIV=O species.
These data rationalize that the activity of these catalysts with respect
to hydrocarbon/alkene oxidation is maximized by maintaining sub-/near-stoichiometric
steady-state concentrations of H2O2, which ensure
that the rate of the H2O2 oxidation by the FeIII–OOH intermediate is less than the rate of the O–O
bond homolysis and the subsequent reaction of the FeIV=O
species with a substrate.

Abstract
This paper presents an accelerated ferrate(VI) (FeVIO42-, FeVI) oxidation of contaminants in 30 s by adding one-electron and two-electron transfer reductants (R(1) and R(2)). An addition of R(2) (e.g., NH2OH, AsIII, SeIV, PIII, and NO2-, and S2O32-) results in FeIV initially, while FeV is generated with the addition of R(1) (e.g., SO32-). R(2) additives, except S2O32-, show the enhanced oxidation of 20-40% of target contaminant, trimethoprim (TMP). Comparatively, enhanced oxidation of TMP was up to 100% with the addition of R(1) to FeVI. Interestingly, addition of S2O32- (i.e., R(2)) also achieves the enhanced oxidation to 100%. Removal efficiency of TMP depends on the molar ratio ([R(1)]:[FeVI] or [R(2)]:[FeVI]). Most of the reductants have the highest removal at molar ratio of ∼0.125. A FeVI-S2O32- system also oxidizes rapidly a wide range of organic contaminants (pharmaceuticals, pesticides, artificial sweetener, and X-ray contrast media) in water and real water matrices. FeV and FeIV as the oxidative species in the FeVI-S2O32--contaminant system are elucidated by determining removal of contaminants in oxygenated and deoxygenated water, applying probing agent, and identifying oxidized products of TMP and sulfadimethoxine (SDM) by FeVI-S2O32- systems. Significantly, elimination of SO2 from sulfonamide (i.e., SDM) is observed for the first time.

Abstract
![]()
Non-heme iron(II)
complexes of pentadentate N4Py (N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine)
type ligands undergo visible light-driven oxidation to their iron(III)
state in the presence of O2 without ligand degradation.
Under mildly basic conditions, however, highly selective base catalyzed
ligand degradation with O2, to form a well-defined pyridyl-imine
iron(II) complex and an iron(III) picolinate complex, is accelerated
photochemically. Specifically, a pyridyl-CH2 moiety is
lost from the ligand, yielding a potentially N4 coordinating ligand
containing an imine motif. The involvement of reactive oxygen species
other than O2 is excluded; instead, deprotonation at the
benzylic positions to generate an amine radical is proposed as the
rate determining step. The selective nature of the transformation
holds implications for efforts to increase catalyst robustness through
ligand design. Photoaccelerated oxidation
of an aminopyridyl ligand bound
to an Fe(III) ion to a well-defined imine-based Fe(II) complex involves
initial alkyl C−H deprotonation followed by reaction with O2 to form an alkyl peroxyl radical. Intramolecular C−H
abstraction followed by C−N bond cleavage yields picoline aldehyde
and a pyridyl-imine complex. The selectivity of the reaction prevents
further oxidation and holds implications for ligand degradation under
conditions used in oxidation catalysis with peroxides.

Abstract
Non‐heme (L)FeIII and (L)FeIII‐O‐FeIII(L) complexes (L=1,1‐di(pyridin‐2‐yl)‐N,N‐bis(pyridin‐2‐ylmethyl)ethan‐1‐amine) underwent reduction under irradiation to the FeII state with concomitant oxidation of methanol to methanal, without the need for a secondary photosensitizer. Spectroscopic and DFT studies support a mechanism in which irradiation results in charge‐transfer excitation of a FeIII−μ‐O−FeIII complex to generate [(L)FeIV=O]2+ (observed transiently during irradiation in acetonitrile), and an equivalent of (L)FeII. Under aerobic conditions, irradiation accelerates reoxidation from the FeII to the FeIII state with O2, thus closing the cycle of methanol oxidation to methanal.
