The substitution reaction of ferrocenyl alcohol with various nucleophiles catalyzed by cerium ammonium nitrate (CAN) was investigated. This CAN-mediated direct carbon-carbon bond formation provides the corresponding products in moderate to high yields with relatively lower catalyst loading (5 mol %) at room temperature. It demonstrated a convenient synthetic protocol for the ferrocene functionalities. Crown Copyright

We report the large scale syntheses and ‘oxidative purification’ of fcI2, fcBr2 and FcBr (fc = ferrocene-1,1?-diyl, Fc = ferrocenyl). These valuable starting materials are typically laborious to separate via conventional techniques, but can be readily isolated by taking advantage of their increased E1/2 relative to FcH/FcX contaminants. Our work extends this methodology towards a generic tool for the separation of redox active mixtures.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. category: iron-catalyst, you can also check out more blogs about1293-65-8

Ferrocenyl-chalcones and their bichalcone analogues were characterized by IR and NMR spectroscopy, as well as electrochemically. Their UV?visible spectra were recorded, and the electronic transitions were assigned by time-dependent DFT calculations. The single-crystal X-ray structures were determined for two ferrocenyl bichalcones.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1271-48-3, and how the biochemistry of the body works.Reference of 1271-48-3

Phospholipase D (Pld) Is A Useful Enzyme For Its Transphosphatidylation Activity, Which Enables The Enzymatic Synthesis Of Various Phospholipids (Pls). Many Reports Exist On Pld-Mediated Synthesis Of Natural And Tailor-Made Pls With Functional Head Groups, From Easily Available Lecithin Or Phosphatidylcholine. Early Studies On Pld-Mediated Synthesis Mainly Employed Enzymes Of Plant Origin, Which Were Later Supplanted By Ones From Microorganisms, Especially Actinomycetes. Many Plds Are Members Of The Pld Superfamily, Having One Or Two Copies Of A Signature Sequence, Hxkxxxxd Or Hkd Motif, In The Primary Structures. Pld Superfamily Members Share A Common Core Structure, And Thereby, A Common Catalytic Mechanism. The Catalysis Proceeds Via Two-Step Reaction With The Formation Of Phosphatidyl-Enzyme Intermediate. Both Of The Two Catalytic His Residues Are Critical In The Reaction Course, Where One Acts As A Nucleophile, While The Other Functions As A General Acid/Base. Pld Is Being Engineered To Improve Its Activity And Stability, Alter Head Group Specificity And Further Identify Catalytically Important Residues. Since The Knowledge On Pld Enzymology Is Constantly Expanding, This Review Focuses On Recent Advances In The Field, Regarding Pld-Catalyzed Synthesis Of Bioactive Pls, Deeper Understanding Of Substrate Recognition And Binding Mechanism, Altering Substrate Specificity, And Improving Thermostability. We Introduced Some Of Our Recent Results In Combination With Existing Facts To Further Deepen The Story On The Nature Of This Useful Enzyme.

Photocatalytic oxidation of iron(ii) complexes by dioxygen occurred using the organic photocatalysts, 9-mesityl-10-methylacridinium ions (Acr+-Mes) and 2-phenyl-4-(1-naphthyl) quinolinium ions (QuPh+-NA), in the presence of triflic acid in acetonitrile under visible light irradiation. The electron-transfer state of Acr+-Mes produced upon photoexcitation oxidized the iron(ii) complexes, whereas it reduced dioxygen with protons to produce iron(iii) complexes and H2O2.

A multicomponent multicatalyst reaction (MC)2R for constructing fully substituted 1,2,3-triazoles is reported. An application of chemoselectivity and latent catalysis in a sequence of multicatalytic reactions confers control over a number of undesired processes, where all of the reagents coexist in the same reaction vessel. The sequence of a chemoselective copper-catalyzed azide alkyne cycloaddition followed by a palladium/copper-catalyzed Sonogashira cross-coupling afforded 1,2,3-triazoles regioselectively with good to high yields and a broad scope.

To determine the trans effect on the rates of reductive eliminations from arylpalladium(II) amido complexes, the reactions of arylpalladium amido complexes bearing symmetrical and unsymmetrical DPPF (DPPF = bis(diphenylphosphino)ferrocene) derivatives were studied. THF solutions of LPd(Ar)(NMeAr?) (L = DPPF, DPPF-OMe, DPPF-CF3, DPPF-OMe,Ph, DPPF-Ph,CF3, and DPPF-OMe,CF3; Ar = C6H 4-4-CF3; Ar? = C6H4-4-CH 3, Ph, and C6H4-4-OMe) underwent C-N bond forming reductive elimination at -15 C to form the corresponding N-methyldiarylamine in high yield. Complexes ligated by symmetrical DPPF derivatives with electron-withdrawing substituents on the DPPF aryl groups underwent reductive elimination faster than complexes ligated by symmetrical DPPF derivatives with electron-donating substituents on the ligand aryl groups. Studies of arylpalladium amido complexes containing unsymmetrical DPPF ligands revealed several trends. First, the complex with the weaker donor trans to nitrogen and the stronger donor trans to the palladium-bound aryl group underwent reductive elimination faster than the regioisomeric complex with the stronger donor trans to nitrogen and the weaker donor trans to the palladium-bound aryl group. Second, the effect of varying the substituents on the phosphorus donor trans to the nitrogen was larger than the effect of varying the substituents on the phosphorus donor trans to the palladium-bound aryl group. Third, the difference in rate between the isomeric arylpalladium amido complexes was similar in magnitude to the differences in rates resulting from conventional variation of substituents on the symmetric phosphine ligands. This result suggests that the geometry of the complex is equal in importance to the donating ability of the dative ligands. The ratio of the differences in rates of reaction of the isomeric complexes was similar to the relative populations of the two geometric isomers. This result and consideration of transition state geometries suggest that the reaction rates are controlled more by substituent effects on ground state stability than on transition state energies. In addition, variation of the aryl group at the amido nitrogen showed systematically that complexes with more electron-donating groups at nitrogen undergo faster reductive elimination than those with less electron-donating groups at nitrogen.
