So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Huang, Long; Ji, Tengfei; Rueping, Magnus researched the compound: Nickel(II) chloride ethylene glycol dimethyl ether complex( cas:29046-78-4 ).Reference of Nickel(II) chloride ethylene glycol dimethyl ether complex.They published the article 《Remote Nickel-Catalyzed Cross-Coupling Arylation via Proton-Coupled Electron Transfer-Enabled C-C Bond Cleavage》 about this compound( cas:29046-78-4 ) in Journal of the American Chemical Society.

Cross-coupling reactions for carbon-carbon and carbon-heteroatom bond formation are of great importance in modern chem. synthesis. In addition to classical cross-couplings involving preformed or preactivated coupling partners, more recently breakthroughs have been made in the selective, direct coupling of abundant aliphatic carbon-hydrogen bonds using hydrogen atom transfer reactions in which the bond-dissociation energy is the thermodn. driving force. The more challenging carbon-carbon bond activation is still rather underdeveloped due to the bond inertness. Herein, we report a mild and general strategy for the activation of a diverse set of readily available cyclic alcs. for the remote and site-specific arylation of ketones via the combination of photoredox-mediated multisite concerted proton-electron transfer (MS-PCET) and nickel catalysis. The current cross-coupling proceeds with the generation of an alkoxy radical utilizing bond-dissociation free energy (BDFE) as the thermodn. driving force. Subsequently, the resulting remote carbon-centered radicals formed by C-C cleavage merge with the nickel catalytic cycle to create the challenging C(sp3)-C(sp2) bonds.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry.

Historically accessed through two-electron, anionic chem., ketones, alcs., and amines are of foundational importance to the practice of organic synthesis. After placing this work in proper historical context, this Article reports the development, full scope, and a mechanistic picture for a strikingly different way of forging such functional groups. Thus, carboxylic acids, once converted to redox-active esters (RAEs), can be utilized as formally nucleophilic coupling partners with other carboxylic derivatives (to produce ketones), imines (to produce benzylic amines), or aldehydes (to produce alcs.). The reactions are uniformly mild, operationally simple, and, in the case of ketone synthesis, broad in scope (including several applications to the simplification of synthetic problems and to parallel synthesis). Finally, an extensive mechanistic study of the ketone synthesis is performed to trace the elementary steps of the catalytic cycle and provide the end-user with a clear and understandable rationale for the selectivity, role of additives, and underlying driving forces involved.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 29046-78-4, is researched, Molecular C4H10Cl2NiO2, about Generation and Oxidative Reactivity of a Ni(II) Superoxo Complex via Ligand-Based Redox Non-Innocence, the main research direction is hydrazono tolyl pyrrolo nickel complex preparation crystal mol structure; superoxo nickel hydrazono tolyl pyrrolo preparation oxidation alc hydrocarbon.Application of 29046-78-4.

Metal ligand cooperativity is a powerful strategy in transition metal chem. This type of mechanism for the activation of O2 is best exemplified by heme centers in biol. systems. While aerobic oxidations with Fe and Cu are well precedented, Ni-based oxidations are frequently less common due to less-accessible metal-based redox couples. Some Ni enzymes use special ligand environments for tuning the Ni(II)/(III) redox couple such as strongly donating thiolates in Ni superoxide dismutase. A recently characterized example of a Ni-containing protein, however, suggests an alternative strategy for mediating redox chem. with Ni by using ligand-based reducing equivalent to enable O binding. While this mechanism has little synthetic precedent, the authors show here that Ni complexes of the redox-active ligand tBu,TolDHP (tBu,TolDHP = 2,5-bis((2-t-butylhydrazono)(p-tolyl)methyl)-pyrrole) activate O2 to generate a Ni(II) superoxo complex via ligand-based electron transfer. This superoxo complex is competent for stoichiometric oxidation chem. with alcs. and hydrocarbons. Coupling ligand-based redox chem. with functionally redox-inactive Ni centers enables oxidative transformations more commonly mediated by metals such as Fe and Cu.

Author is Arauzo, Ana; Cabeza, Javier A.; Fernandez, Israel; Garcia-Alvarez, Pablo; Garcia-Rubio, Ines; Laglera-Gandara, Carlos J..

The reactivity of the PGeP germylene 2,2′-bis(di-isopropylphosphanylmethyl)-5,5′-dimethyldipyrromethane-1,1′-diylgermanium(II), Ge(pyrmPiPr2)2CMe2, with late first-row transition metal (Fe-Zn) dichlorides has been investigated. All reactions led to PGeP pincer chloridogermyl complexes. The reactions with FeCl2 and CoCl2 afforded paramagnetic square planar complexes of formula [MCl{κ3P,Ge,P-GeCl(pyrmPiPr2)2CMe2}] (M = Fe, Co). While the iron complex maintained an intermediate spin state (S1; μeff = 3.0μB) over the temperature range 50-380 K, the effective magnetic moment of the cobalt complex varied linearly with temperature from 1.9μB at 10 K to 3.6μB at 380 K, indicating a spin crossover behavior that involves S1/2 (predominant at T<180 K) and S3/2 (predominant at T>200 K) species. Both cobalt(II) species were detected by ESR at T<20 K. The reaction of Ge(pyrmPiPr2)2CMe2 with [NiCl2(dme)] (dme = dimethoxyethane) gave a square planar nickel(II) complex, [NiCl{κ3P,Ge,P-GeCl(pyrmPiPr2)2CMe2}], whereas the reaction with CuCl2 involved a redox process that rendered a mixture of the germanium(IV) compound GeCl2(pyrmPiPr2)2CMe2 and a binuclear copper(I) complex, [Cu2{μ-κ3P,Ge,P-GeCl(pyrmPiPr2)2CMe2}2], whose metal atoms are in tetrahedral environments. The reaction of the germylene with ZnCl2 led to the tetrahedral derivative [ZnCl{κ3P,Ge,P-GeCl(pyrmPiPr2)2CMe2}].

C-Glycosides are metabolically stable mimics of natural O-glycosides and are expected to be useful tools for investigation of the biol. functions of glycans. Here, we describe the synthesis of a series of aryl and vinyl C-glycosides by stereoinvertive sp3-sp2 cross-coupling reactions of 2-deoxyglycosyl boronic acid derivatives with aryl or vinyl halide, mediated by a photoredox/nickel dual catalytic system.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds.

Cross-coupling of two alkyl fragments is an efficient method to produce organic mols. rich in sp3-hybridized carbon centers, which are attractive candidate compounds in drug discovery. Enantioselective C(sp3)-C(sp3) coupling is challenging, especially of alkyl electrophiles without an activating group (aryl, vinyl, carbonyl). Here, we report a strategy based on nickel hydride addition to internal olefins followed by nickel-catalyzed alkyl-alkyl coupling. This strategy enables the enantioselective cross-coupling of non-activated alkyl halides with alkenyl boronates to produce chiral alkyl boronates. Employing readily available and stable olefins as pro-chiral nucleophiles, the coupling proceeds under mild conditions and exhibits broad scope and high functional-group tolerance. Applications for the functionalization of natural products and drug mols., as well as the synthesis of chiral building blocks and a key intermediate to (S)-(+)-pregabalin, are demonstrated.

Photochem. decarboxylation, arylation and borylation of carboxylic acids and α-amino acids catalyzed by 1,2,3,5-tetracarbazolyl. The synthesis of complex alkyl boronic esters through conjunctive cross-coupling of vinyl boronic esters with carboxylic acids and aryl iodides is described. The reaction proceeds under mild metallaphotoredox conditions and involves an unprecedented decarboxylative radical addition/cross-coupling cascade of vinyl boronic esters. Excellent functional-group tolerance is displayed, and application of a range of carboxylic acids, including secondary α-amino acids, and aryl iodides provides efficient access to highly functionalized alkyl boronic esters. The decarboxylative conjunctive cross-coupling was also applied to the synthesis of sedum alkaloids.

The broad reaction scope and good yields of the Ni-catalyzed electrochem. coupling reactions were confirmed by 50 examples of aryl/β-styrenyl chloride/bromide and benzylic trifluoroborates. Potential applications were demonstrated by electrosynthesis and late-stage functionalization of pharmaceuticals and natural amino acid modification, and three reactions were run on gram-scale in a flow-cell electrolyzer. The electrochem. C-C cross-coupling reactions proceed through an unconventional radical transmetalation mechanism. This method is highly productive and expected to find wide-spread applications in organic synthesis.
