Author is Ociepa, Michal; Wierzba, Aleksandra J.; Turkowska, Joanna; Gryko, Dorota.

Strain-release-driven methodol. is a powerful tool for accessing structural motifs, highly desirable by the pharmaceutical industry. The reactivity of spring-loaded cyclic reagents is dominated by transformations relying on their inherent electrophilic reactivity. Herein, we present a polarity-reversal strategy based on light-driven cobalt catalysis, which enables the generation of nucleophilic radicals through strain release. The applicability of this methodol. is demonstrated by the design of two distinct types of reactions: Giese-type addition and Co/Ni-catalyzed cross-coupling. Moreover, a series of electrochem., spectroscopic, and kinetic experiments as well as X-ray structural anal. of the intermediate alkylcobalt(III) complex give deeper insight into the mechanism of the reaction.

Cycloalkanone oxime O-pentafluorobenzoyl esters such as I underwent tandem ring opening, radical addition, and cyclization reactions with arylalkenyl azides via iminyl radicals. In the presence of NiCl2·diglyme, cyclobutanone oxime O-pentafluorobenzoyl esters underwent ring opening, radical addition, and cyclization reactions with arylalkenyl azides such as PhC(N3):CH2 to yield dihydropyrroleacetonitriles such as II. In the presence of either NiCl2·diglyme or FeSO4, cycloalkanone oxime O-pentafluorobenzoyl esters underwent ring opening, radical addition, and cyclization reactions with biarylalkenyl azides such as 2-(1-azidoethenyl)-1,1′-biphenyl to yield phenanthrolinealkanenitriles such as III. The reactions were inhibited by TEMPO or BHT; azirines were formed but were not intermediates in the reactions.

Compound: Nickel(II) chloride ethylene glycol dimethyl ether complex, is researched, Molecular C4H10Cl2NiO2, CAS is 29046-78-4, about Catalyst-controlled doubly enantioconvergent coupling of racemic alkyl nucleophiles and electrophiles. Author is Huo, Haohua; Gorsline, Bradley J.; Fu, Gregory C..

Stereochem. control in the construction of carbon-carbon bonds between an alkyl electrophile and an alkyl nucleophile is a persistent challenge in organic synthesis. Classical substitution reactions via SN1 and SN2 pathways are limited in their ability to generate carbon-carbon bonds (inadequate scope, due to side reactions such as rearrangements and eliminations) and to control stereochem. when beginning with readily available racemic starting materials (racemic products). Here, we report a chiral nickel catalyst that couples racemic electrophiles (propargylic halides) with racemic nucleophiles (β-zincated amides) to form carbon-carbon bonds in doubly stereoconvergent processes, affording a single stereoisomer of the product from two stereochem. mixtures of reactants.

The development and scale up of a nickel-catalyzed reductive cross-electrophile coupling reaction between a substituted 2-chloropyridine and Et 3-chloropropanoate using manganese dust as the terminal reductant is reported. Several additives were screened for the activation of the manganese reductant in situ, and TESCl was found to provide the optimal conversion. A Focused Beam Reflectance Measurement (FBRM) probe was utilized to monitor particle attrition as well as manganese activation during the reaction. Modeling was employed to garner an understanding of mixing requirements that would ensure effective suspension of the manganese during scale-up. The process was successfully demonstrated on a 7 kg scale and afforded >60% yield of compound I.

A variety of 2-boryl-1,1-diarylalkanes, which constitute a class of significant pharmacophores, are efficiently prepared from readily available olefins and aryl halides in the presence of bis(pinacolato)diboron under mild reaction conditions.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Nickel-Catalyzed Regioselective Hydroalkylation and Hydroarylation of Alkenyl Boronic Esters, published in 2019, which mentions a compound: 29046-78-4, Name is Nickel(II) chloride ethylene glycol dimethyl ether complex, Molecular C4H10Cl2NiO2, Formula: C4H10Cl2NiO2.

Metal hydride catalyzed hydrocarbonation reactions of alkenes are an efficient approach to construct new C-C bonds from readily available alkenes. However, the regioselectivity of hydrocarbonation remains challenging to be controlled. In Ni hydride (NiH) catalyzed hydrocarbonation, linear selectivity is most often obtained because of the relative stability of the linear Ni-alkyl intermediate over its branched counterpart. Herein, the boronic pinacol ester (Bpin) group directs a Ni-catalyzed hydrocarbonation to occur at its adjacent C center, resulting in formal branch selectivity. Both alkyl and aryl halides can be used as electrophiles in this hydrocarbonation, providing access to a wide range of secondary alkyl Bpin derivatives, which are valuable building blocks in synthetic chem. The utility of the method is demonstrated by the late-stage functionalization of natural products and drug mols., the synthesis of an anticancer agent, and iterative syntheses.

A compound: 29046-78-4, is researched, SMILESS is COCCOC.Cl[Ni]Cl, Molecular C4H10Cl2NiO2Journal, Article, Dalton Transactions called Heterobimetallic complexes of IrM (M = FeII, CoII, and NiII) core and bridging 2-(diphenylphosphino)pyridine: electronic structure and electrochemical behavior, Author is Cherepakhin, Valeriy; Hellman, Ashley; Lan, Zhenzhuo; Mallikarjun Sharada, Shaama; Williams, Travis J., the main research direction is heterobimetallic transition metal diphenylphosphinopyridine complex preparation crystal structure; DFT heterobimetallic transition metal diphenylphosphinopyridine complex; cyclic voltammetry heterobimetallic transition metal diphenylphosphinopyridine complex.HPLC of Formula: 29046-78-4.

Three complexes based on an Ir-M (M = FeII, CoII, and NiII) heterobimetallic core and 2-(diphenylphosphino)pyridine (Ph2PPy) ligand were synthesized via the reaction of trans-[IrCl(CO)(Ph2PPy)2] and the corresponding metal chloride. Their structures were established by single-crystal x-ray diffraction as [Ir(CO)(μ-Cl)(μ-Ph2PPy)2FeCl2]·2CH2Cl2 (2), [IrCl(CO)(μ-Ph2PPy)2CoCl2]·2CH2Cl2 (3), and [Ir(CO)(μ-Cl)(μ-Ph2PPy)2NiCl2]·2CH2Cl2 (4). Time-dependent DFT computations suggest a donor-acceptor interaction between a filled 5dz2 orbital on iridium and an empty orbital on the first-row metal atom, which is supported by UV-visible studies. Magnetic moment measurements show that the first-row metals are in their high-spin electronic configurations. Cyclic voltammetry data show that all the complexes undergo irreversible decomposition upon either reduction or oxidation Reduction of 4 proceeds through an ECE mechanism. While these complexes are not stable to electrocatalysis conditions, the data presented here refine the authors’ understanding of the bonding synergies of the first-row and third-row metals.

This method features a cheap catalyst, mild reaction conditions, and excellent functional group compatibility. The Ni-B(OH)2 complex in situ generated from NiCl2·DME and tetrahydroxydiboron might act as an active catalyst. After three consecutive cis-additions of terminal alkynes, internal migratory insertion cyclization, and β-boron elimination induced aromatization, 1,3,5-trisubstituted benzenes were selectively established.
