Diiron nonacarbonyl oxidized a series of alpha-phenylcarbinols to their corresponding aldehydes and ketones.In addition, this resagent converted 4-methoxybenzyl alcohol to 4-methoxybenzyl ether, albeit in low yield.Under the same reaction conditions, oxidation was a minor with a group of alpha-ferrocenylcarbinols as ether synthesis was the major reaction with those substrates which could not dehydrate; however, stereoselective olefin synthesis predominated when elimination was possible.

In an Article，once mentioned of 1293-65-8

Three [2]ferrocenophanes ([2]FCPs) bridged by nitrogen and silicon (7SiMe2) and nitrogen and tin (7SnMe2, 7SntBu2) were synthesized by salt metathesis between a dilithioferrocene derivative, prepared in situ from 1-bromo-1?-(trimethylsilylamino)ferrocene (6), and Me2SiCl2, Me2SnCl2, and tBu2SnCl2, respectively. A multistep synthesis of precursor 6 is described. Only 7SiMe2 and 7SntBu2 could be prepared as analytically pure compounds. The molecular structures of all three [2]FCPs were determined by single-crystal X-ray analysis. Expectedly, the tilting of the Cp ligands in the silicon species 7SiMe2 is larger [alpha = 15.73(13)] than in the tin compounds 7SnMe2 [alpha = 9.36(17) and 9.45(18)] and 7SntBu2 [alpha = 10.13(11)]. Ring-opening polymerizations of 7SiMe2 and 7SntBu2 were attempted using the common methods of thermal, transition-metal-catalyzed, anionic, and photocontrolled ring-opening polymerization, but none of the experiments gave polymeric materials.

Chemistry involves the study of all things chemical – chemical processes, Safety of 1,1′-Ferrocenedicarboxaldehyde, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations.

The bitopic ligand 1,1?-bis(dipyrazol-1-ylmethyl)ferrocene, Fe[C 5H4CH(pz)2]2 (1; pz = pyrazolyl ring), has been prepared by the reaction of 1,1?-ferrocenedicarbaldehyde and 1,1?-carbonyldipyrazole. In the solid state, the bis(pyrazolyl) methane moieties are in an antiperiplanar eclipsed orientation. The molecules are organized into a three-dimensional array by pi…pi, weak C-H-…N hydrogen bonding, and C-H…pi interactions. The reactions between 1 and AgBF4, AgPF6, AgSO3CF 3, or AgSbF6 yield {Fe[C5H 4CH(pz)2]2AgBF4}n (2), {Fe[C5H4CH(pz)2]2AgPF 6}n (3), {Fe[C5H4CH(Pz) 2]2AgSO3CF3}n (4), and {Fe[C5H4CH(pz2]2AgSbF 6}n (5), respectively. The solid-state structures consist of coordination polymers with compounds 2 and 3 arranged in helical chains, while the chains in 3·1/2Et2O, 4·1.5C6H 6,5·1/2Et2Et2O, and 5·1/2C 6H6 are nonhelical. In these structures, the ferrocenyl groups adopt a similar orientation, where the angle between CH(pz)2 groups is confined to the range of 85-99 and the silver pyrazolyl coordination spheres are also in very similar distorted-tetrahedral arrangements. Both structural types form three-dimensional supramolecular structures organized by weak hydrogen bonds, pi…pi stacking, and CH…pi interactions. In the helical form, the anions reside in the pockets formed by the close-packed chains, whereas in the nonhelical form, sizable channels, which contain the solvent molecules and the anions, are located between the chains.

In a patent，Which mentioned a new discovery about 1273-86-5

A series of ferrocene-appended half-sandwiched iridium(III) phenylpyridine complexes have been designed and synthesized. These complexes show better anticancer activity than cisplatin widely used in clinic under the same conditions. Meanwhile, complexes could effectively inhibit cell migration and colony formation. Complexes could interact with protein and transport through serum protein, effectively catalyzing the oxidation of nicotinamide-adenine dinucleotid and inducing the accumulation of reactive oxygen species (ROS, 1O2), which confirmed the anticancer mechanism of oxidation. Furthermore, laser scanning confocal detection indicates that these complexes can enter cells followed by a non-energy-dependent cellular uptake mechanism, effectively accumulating in the lysosome (Pearson’s colocalization coefficient: ?0.90), leading to lysosome damage, and reducing the mitochondrial membrane potential (MMP). Taken together, ferrocene-appended iridium(III) complexes possess the prospect of becoming a new multifunctional therapeutic platform, including lysosome-targeted imaging and anticancer drugs.

Reactions of Cp2TiMe2, with the ester derivatives of organometallic sandwich compounds (n5-RC5H4)Fe(n5-C5H5) and (n5-RC5H4)Co(n4-C4Ph4) (R=ester groups) gave products having R=C(CH2)Me, instead of the expected vinyl ethers indicating conversion of the ester units by Cp2TiMe2 to methyl ketones followed by methylenation. A reaction of Cp2TiMe2 with the diester (n5-RC5H4)Co(n4-C4Ph3R)(R=C(O)OMe) also gave similar results. The study has also been successfully extended to metal sandwich derived amides, thio and seleno esters. By controlling the amount of Cp2TiMe2, the reactions were also stopped at the methyl ketone stage and the methyl ketones were isolated in good yields and characterized. The method provides an easy and direct access to convert organometallic sandwich derived esters and related compounds to 1-methylvinyl derived products.

He(I) photoelectron (PE) spectra are reported for chloroferrocene Fe(eta-C5H4Cl)(eta-C5H5) and 1,1′-dihalogenoferrocenes Fe(eta-C5H4X)2 (X=Cl, Br).The difference between the ionization potentials (IP’s) of the e2g(d) and a1g(d) level is not affected by the ring substitution.Only the splitting of the e1u(?) level of the ligand is observed in the spectra.From the magnitudes of the splittings of this level and halogen non-bonding orbitals it is concluded that there is significant mixing of iron p orbitals with the e1u(?) level.The spectrum of Fe(eta-C5H4Cl)2 indicates that there is an interaction between the non-bonding out-of-plane chlorine p orbitals.

Vicinal diamines are a common structural motif in bioactive natural products, therapeutic agents, and molecular catalysts, motivating the continuing development of efficient, selective, and sustainable technologies for their preparation. We report an operationally simple and environmentally friendly protocol that converts alkenes and sodium azide?both readily available feedstocks?to 1,2-diazides. Powered by electricity and catalyzed by Earth-abundant manganese, this transformation proceeds under mild conditions and exhibits exceptional substrate generality and functional group compatibility. Using standard protocols, the resultant 1,2-diazides can be smoothly reduced to vicinal diamines in a single step, with high chemoselectivity. Mechanistic studies are consistent with metal-mediated azidyl radical transfer as the predominant pathway, enabling dual carbon-nitrogen bond formation.

Diaphorase (DI) works as an effective catalyst for the electrochemical oxidation and reduction of NAD with the aid of several quinones or flavins as electron transfer mediators. The redox kinetics between DI and mediators have been expressed by a Butler-Volmer-type equation. NAD-dependent L-lactate dehydrogenase (LDH) catalyzing the redox reaction between L-lactate and pyruvate was coupled to the DI-catalyzed NAD redox system to achieve better understanding of mediated two-enzyme-linked bioelectrocatalysis with reversible characteristics. Under the conditions where the concentration polarization of NAD due to the DI-catalyzed electrochemical reaction is suppressed by the LDH reaction, the NAD concentration dependence of the catalytic current was expressed by an approximate equation involving the enzyme kinetics between DI and NAD. The suppression of the NAD concentration polarization is also useful to observe steady-state catalytic waves of an uphill reaction between DI and the mediator. The oxidation reaction involving the uphill electron transfer from L-lactate to NAD+ is susceptible to a inhibition from pyruvate due to the reversible characteristics of LDH. The present knowledge has led to the strategy to realize a two-way bioelectrocatalysis for the reduction of pyruvate and the oxidation of L-lactate. New potentiometry for the detection of the solution potential governed by the electrochemically inactive pyruvate/L-lactate redox couple has also been demonstrated based on the reversible characteristics of the DI-DLH-linked bioelectrocatalytic system.
