Author is Malik, Jamal A.; Madani, Amiera; Pieber, Bartholomaeus; Seeberger, Peter H..

Dual photocatalysis and nickel catalysis can effect cross-coupling under mild conditions, but little is known about the in situ kinetics of this class of reactions. We report a comprehensive kinetic examination of a model carboxylate O-arylation, comparing a state-of-the-art homogeneous photocatalyst (Ir(ppy)3) with a competitive heterogeneous photocatalyst (graphitic carbon nitride). Exptl. conditions were adjusted such that the nickel catalytic cycle is saturated with excited photocatalyst. This approach was designed to remove the role of the photocatalyst, by which only the intrinsic behaviors of the nickel catalytic cycles are observed The two reactions did not display identical kinetics. Ir(ppy)3 deactivates the nickel catalytic cycle and creates more dehalogenated side product. Kinetic data for the reaction using Ir(ppy)3 supports a turnover-limiting reductive elimination. Graphitic carbon nitride gave higher selectivity, even at high photocatalyst-to-nickel ratios. The heterogeneous reaction also showed a rate dependence on aryl halide, indicating that oxidative addition plays a role in rate determination The results argue against the current mechanistic hypothesis, which states that the photocatalyst is only involved to trigger reductive elimination.

From this literature《Evidence for Photocatalyst Involvement in Oxidative Additions of Nickel-Catalyzed Carboxylate O-Arylations》,we know some information about this compound(29046-78-4)Name: Nickel(II) chloride ethylene glycol dimethyl ether complex, but this is not all information, there are many literatures related to this compound(29046-78-4).

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.Cheng, Ran; Sang, Yueqian; Gao, Xing; Zhang, Shu; Xue, Xiao-Song; Zhang, Xingang researched the compound: Nickel(II) chloride ethylene glycol dimethyl ether complex( cas:29046-78-4 ).Name: Nickel(II) chloride ethylene glycol dimethyl ether complex.They published the article 《Highly γ-Selective Arylation and Carbonylative Arylation of 3-Bromo-3,3-difluoropropene via Nickel Catalysis》 about this compound( cas:29046-78-4 ) in Angewandte Chemie, International Edition. Keywords: regioselective arylation carbonylation bromodifluoropropene nickel catalysis; 3-bromo-3,3-difluoropropene; arylboronic acids; carbonylation; gem-difluoroalkenes; nickel catalysis. We’ll tell you more about this compound (cas:29046-78-4).

A nickel-catalyzed highly γ-regioselective arylation and carbonylative arylation of 3-bromo-3,3-difluoropropene has been developed. The reaction proceeds under mild reaction conditions, providing the gem-difluoroalkenes with high efficiency and good functional group tolerance. The resulting gem-difluoroalkenes can serve as versatile building blocks for diversified synthesis. Preliminary mechanistic studies and d. functional theory calculations reveal that both non-radical and radical pathways are possible for the reaction, and the radical pathway is more likely. The high γ-regioselectivity results from the β-bromide elimination of alkylnickel(II) species or from the reductive elimination of nickel(III) species [(aryl)(CF2=CHCH2)NiIII(Ln)X]. The γ-selective carbonylation of 3-bromo-3,3-difluoropropene under 1 atm CO gas also provides a new way for nickel-catalyzed carbonylation. Thus, e.g., (4-tert-butylphenyl)boronic acid + 3-bromo-3,3-difluoropropene → I (86%, 84% isolated) in presence of NiCl2.DME and bpy.

Author is Xiao, Jichao; Li, Zhenning; Montgomery, John.

The addition of alkyl fragments to aliphatic aldehydes is a highly desirable transformation for fragment couplings, yet existing methods come with operational challenges related to the basicity and instability of the nucleophilic reagents commonly employed. Herein, use of nickel catalyst alongwith a readily available bioxazoline (BiOx) ligand to catalyze the reductive coupling of redox-active esters with aliphatic aldehydes using zinc metal as the reducing agent to deliver silyl-protected secondary alcs. is reported. This protocol is operationally simple, proceeds under mild conditions, and tolerates a variety of functional groups. Initial mechanistic studies suggest a radical chain pathway. Addnl., alkyl tosylates and epoxides are suitable alkyl precursors to this transformation providing a versatile suite of catalytic reactions for the functionalization of aliphatic aldehydes.

We report a NiH-catalyzed migratory defluorinative coupling between two electronically differentiated olefins. A broad range of unactivated donor olefins can be joined directly to acceptor olefins containing an electron-deficient trifluoromethyl substituent in both intra- and intermol. fashion to form gem-difluoroalkenes. This migratory coupling shows both site- and chemoselectivity under mild conditions, with the formation of a tertiary or quaternary carbon center.

Author is Yue, Huifeng; Zhu, Chen; Kancherla, Rajesh; Liu, Fangying; Rueping, Magnus.

Alkynes are an important class of organic mols. due to their utility as versatile building blocks in synthesis. Although efforts have been devoted to the difunctionalization of alkynes, general and practical strategies for the direct hydroalkylation and alkylarylation of terminal alkynes under mild reaction conditions are less explored. Herein, a photoredox/nickel dual-catalyzed anti-Markovnikov-type hydroalkylation of terminal alkynes as well as a one-pot arylalkylation of alkynes with alkyl carboxylic acids and aryl bromides via a three-component cross-coupling has been discussed. The results indicate that the transformations proceed via a new mechanism involving a single-electron transfer with subsequent energy-transfer activation pathways. Moreover, steady-state and time-resolved fluorescence-spectroscopy measurements, d. functional theory (DFT) calculations, and wavefunction anal. have been performed to give an insight into the catalytic cycle.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

A scalable enantioselective nickel-catalyzed electrochem. reductive homocoupling of aryl bromides has been developed, affording enantioenriched axially chiral biaryls in good yield under mild conditions using electricity as a reductant in an undivided cell [e.g., 2-(benzyloxy)-1-bromonaphthalene → (R)-2,2′-bis(benzyloxy)-1,1′-binaphthyl (72% yield (65% isolated), 93% ee) using a chiral indan-fused oxazoline and NiCl2.glyme in presence of mol. sieves]. Common metal reductants such as Mn or Zn powder resulted in significantly lower yields in the absence of elec. current under otherwise identical conditions, underscoring the enhanced reactivity provided by the combination of transition metal catalysis and electrochem.

Kim, Weonjeong; Koo, Jangwoo; Lee, Hong Geun published the article 《Benzylic C(sp3)-C(sp2) cross-coupling of indoles enabled by oxidative radical generation and nickel catalysis》. Keywords: benzylic indole preparation; indole aryl halide arylation cross coupling photocatalyst; acyl indole preparation; acid anhydride indole acylation cross coupling photocatalyst.They researched the compound: Nickel(II) chloride ethylene glycol dimethyl ether complex( cas:29046-78-4 ).Recommanded Product: 29046-78-4. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:29046-78-4) here.

A mechanistically unique functionalization strategy for a benzylic C(sp3)-H bond was developed based on facile oxidation event of indole substrates. This novel pathway was initiated by efficient radical generation at benzylic position of substrate, with subsequent transition metal catalysis to complete overall transformation. Ultimately, an aryl or an acyl group could be effectively delivered from an aryl (pseudo)halide or an acid anhydride coupling partner, resp. The developed method utilized mild conditions and exhibited a wide substrate scope for both substituted indoles and C(sp2)-based reaction counterparts. Mechanistic studies showed that competitive hydrogen atom transfer (HAT) processes, which were frequently encountered in conventional methods, are not involved in the product formation process of the developed strategy.
