Non-aggregated ruthenium naphthalocyanine enabling homogeneous carbene insertion into N-H bonds at low catalyst loading

Dalton Transactions, Год журнала: 2025, Номер 54(10), С. 4018 - 4024

Опубликована: Янв. 1, 2025

The first highly efficient Ru naphthalocyanine catalyst for conversion of amines to glycine derivatives has been developed. Unlike widely studied phthalocyanine counterparts, metal naphthalocyanines were not yet described as homogeneous catalysts.

Doubly Stereogenic Sandwich Frameworks: Diastereomeric Metallobiscorroles

Inorganic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Май 4, 2025

A number of Group 6 metallobiscorrole sandwich compounds with square-antiprismatic coordination were separated into diastereomers by means careful preparative thin-layer chromatography. The differ respect to the relative orientation corrole macrocycles, which are rotated approximately ± 45° or 135° each other. most clear-cut results obtained for two tungsten corroles, W[TBCF3PC]2 {TBCF3PC = meso-tris[3,5-bis(trifluoromethyl)phenyl]corrolato} and W[TDOMePC]2 [TDOMePC meso-tris(3,5-dimethoxyphenyl)corrolato], single-crystal X-ray structures diastereomer; existence diastereomer was inferred elimination support from DFT calculations. For Mo[TBCF3PC]2 W[TBCF3PC]2, both also fully characterized spectroscopically their 1H NMR spectra essentially assigned. fact that is chiral exists as enantiomers (which previously demonstrated form a biscorrole) establishes doubly stereogenic nature framework - our knowledge, first such demonstration compound.

C–H Bond Activation by an Antimony(V) Oxo Intermediate Accessed through Electrochemical Oxidation of Antimony(III) Tetrakis(thiocyano)corrole

Inorganic Chemistry, Год журнала: 2023, Номер 62(46), С. 18779 - 18788

Опубликована: Ноя. 7, 2023

A new class of antimony(III) corroles has been described. The photophysical properties these newly synthesized tetrakis(thiocyano)corrolatoantimony(III) derivatives having four SCN groups on the bipyrrole unit corrole are drastically altered compared to their β-unsubstituted corrolatoantimony(III) analogues. UV–vis and emission spectra significantly red-shifted (roughly 30–40 nm) in comparison with derivatives. Q bands strengthened. intensity most prominent band is roughly 70% that Soret absorbs strongly at far-red region, i.e., 700–720 nm. These molecules emit light near-infrared region (700–900 nm). Tetrakis(thiocyano)corrolatoantimony(III) undergoes electrochemical anodic oxidation form SbV═O species, which facilitates electrocatalytic oxygen evolution reaction (OER) activation benzylic C–H produce benzoic acid selectively. Under optimized conditions, SbIII-corrole@NF (NF = nickel foam) required an overpotential 380 mV reach a 50 mA cm–2 current density, comparable those other transition-metal-based complexes. On hand, replacing OER benzyl alcohol lowered potential by 150 (at 300 cm–2) improve energy efficiency process.

Inverse Hypercorroles

Опубликована: Янв. 29, 2024

Ground-state and time-dependent density functional theory (TDDFT) calculations with the long-range-corrected, Coulomb-attenuating CAMY-B3LYP exchange-correlation large, all-electron STO-TZ2P basis sets have been used to examine potential “inverse hypercorrole” character of meso-p-nitrophenyl-appended dicyanidocobalt(III) corrole dianions. The effect is most dramatic for 5,15-bis(p-nitrophenyl) derivatives, where it manifests itself in intense NIR absorptions. 10-aryl groups these complexes play a minor modulatory role. TDDFT (CAMY-B3LYP) ascribe features clearly transition from corrole’s a2u- like HOMO (retaining D4h irrep metalloporphyrins) nitrophenyl-based LUMO. outward nature this contrasts usual phenyl-to-macrocycle direction charge transfer transitions many hyperporphyrins hypercorroles. studied, therefore, are aptly described as inverse

Tris(pentafluorophenyl)corrolatoindium(III) – A Long-awaited Metallocorrole: Synthesis and Characterization

Journal of the Turkish Chemical Society Section A Chemistry, Год журнала: 2024, Номер 11(2), С. 803 - 812

Опубликована: Апрель 8, 2024

The first attempts at the synthesis of an indium corrole compound were synthesized in late 80s, but it has not been possible to obtain and characterize such complex completely, part metallocorrole’s periodic table remained unfilled. In this work, efficient insertion into 5,10,15-tris(pentafluorophenyl)corrole was achieved. obtained 5,10,15-tris(pentafluorophenyl)corrolato indium(III) derivatives successfully characterized by relevant analytical techniques some photophysical electrochemical features studied investigated for time. As a novel research, 19F-19F COSY NMR technique employed time chemistry results further compared geometry-optimized molecular structure via density functional theory (DFT) calculations.

Given the relative scarcity of cobalt in earth's crust, its retention biological systems, principally (but not exclusively) corrinoids or derivatives vitamin B12, may be surprising. The chemistry these compounds and much more widely utilized iron porphyrins, is compared contrasted an attempt made to explain biology.
