Trapali, Adelais published the artcileImbroglio at a photoredox-iron-porphyrin catalyst dyad for the photocatalytic CO2 reduction, Safety of 1,3-Dimethoxybenzene, the main research area is iron porphyrin complex preparation photocatalytic carbon dioxide reduction.

We have covalently connected the ruthenium trisbipyridine complex (bpyRu) as a photoredox module to an iron porphyrin catalyst (porFe) through an amido function for investigating the synergistic action to power the photocatalytic CO2 reduction The electrochem. studies of the porFe-bpyRu dyad did not show any marked effect on the redox properties of the constitutive units. However, the photophys. properties of the porFe-bpyRu dyad point to the complete extinction of the photoredox module that undergoes ultrafast quenching processes with the porFe acolyte, the unavoidable dilemma in this type of mol. assemblies. Nevertheless, when exogenous bpyRu and a sacrificial electron donor were added to this dyad, we found that it exhibits much higher turnover number and selectivity towards CO2 photocatalytic reduction to CO than with the iron porphyrin analog (porFe). Comprehensive analyses of the data suggest that this catalytic enhancement displayed by the dyad can be attributed to an interesting electron relay role played by the appended bpyRu moiety.

Du, Tianshu published the artcileTheoretical O-CH3 bond dissociation enthalpies of selected aromatic and non-aromatic molecules, Name: 1,3-Dimethoxybenzene, the main research area is aromatic compound bond cleavage enthalpy.

Although Me transfer reactions are important in both chem. and biol. systems, there is a need for thermodn. parameters related to Me affinity and O-CH3 bond dissociation enthalpies (BDEs) relevant to a full understanding of the mechanisms of Me transfer reactions. As a prelude to the construction of a database of O-CH3 BDEs, the present work examines the reliability of a series of theor. methods for the prediction of O-CH3 BDEs using a set of 25 compounds that included both aromatic and non-aromatic mols. The BDEs calculated by d. functional theory (DFT) with traditional exchange-correlation functions exhibited much larger errors than those obtained by either the M06-2X or G4 methods. For the non-aromatic compounds, M06-2X/def2-TZVP performed slightly better than G4, but G4 was more accurate for the aromatic mols. As a result, we recommend G4 as the preferred method for the theor. estimation of O-CH3 bond dissociation enthalpies, although M06-2X may be a good alternative for large complex mols. when the use of G4 is impractical.

Zhao, Xin published the artcileCu-Catalyzed Intermolecular γ-Site C-H Amination of Cyclohexenone Derivatives: The Benefit of Bifunctional Ligands, Synthetic Route of 5961-59-1, the main research area is aniline cyclohexenone copper catalyst regioselective amination green chem; amino alc preparation antibacterial antioxidant; cyclohexadienyl oxy silyl ether aniline copper regioselective diastereoselective amination; aminocyclohexenone preparation green chem.

Utilizing 1,10-phenanthroline-type bifunctional ligands, an efficient Cu-catalyzed intermol. site-selective remote C-H amination using cyclohexenone derivatives and anilines was realized. The amide group installed on the bifunctional ligand played a key role in stabilizing the N-centered radical generated in-situ to realize C-N-directed formation. Meanwhile, a useful catalytic system for site-selective intermol. remote γ-C-H amination to p-aminophenols and γ-aminated enones was established. This economical and practical approach using oxygen as the terminal oxidant was mild and environmentally friendly.

Levinn, Carolyn M. published the artcileN-Methylation of Self-Immolative Thiocarbamates Provides Insights into the Mechanism of Carbonyl Sulfide Release, Quality Control of 5961-59-1, the main research area is self immolative methylated thiocarbamate carbonyl sulfide release mechanism.

Hydrogen sulfide (H2S) is an important biomol., and self-immolative thiocarbamates have shown great promise as triggerable H2S donors with suitable analogous control compounds; however, thiocarbamates with electron-deficient payloads are less efficient H2S donors. We report here the synthesis and study of a series of N-methylated esterase-triggered thiocarbamates that block the postulated unproductive deprotonation-based pathway for these compounds The relative reaction profiles for H2S release across a series of electron-rich and electron-poor N-Me aniline payloads are examined exptl. and computationally. We show that thiocarbamate N-methylation does block some side reactivity and increases the H2S release profiles for electron-poor donors. Addnl., we show that isothiocyanate release is not a competitive pathway, and rather that the reduced efficiency of electron-poor donors is likely due to other side reactions.

A practical single-electron-transfer-induced selective C(sp3)-N coupling of cycloketoximes with anilines via C-C bond cleavage under copper-catalytic and synergetic photoredox/copper-catalytic reaction systems has been uncovered. These two powerful and simple protocols demonstrated excellent selectivity and good functional group compatibility without any base or ligand control. Preliminary mechanistic experiments indicated that a radical-mediated process was involved in these transformations.

Nguyen, Vu T. published the artcileVisible-Light-Enabled Direct Decarboxylative N-Alkylation, HPLC of Formula: 5961-59-1, the main research area is visible light decarboxylative alkylation aromatic carbocyclic acid heterocycle amine; acridine catalyst; amination; carboxylic acids; copper catalysis; photocatalysis; visible light.

The development of efficient and selective C-N bond-forming reactions from abundant feedstock chems. remains a central theme in organic chem. owing to the key roles of amines in synthesis, drug discovery, and materials science. Herein, the authors present a dual catalytic system for the N-alkylation of diverse aromatic carbocyclic and heterocyclic amines directly with carboxylic acids, by-passing their preactivation as redox-active esters. The reaction, which is enabled by visible-light-driven, acridine-catalyzed decarboxylation, provides access to N-alkylated secondary and tertiary anilines and N-heterocycles. Addnl. examples, including double alkylation, the installation of metabolically robust deuterated Me groups, and tandem ring formation, further demonstrate the potential of the direct decarboxylative alkylation (DDA) reaction.
