A mild and general nickel-catalyzed asym. reductive hydroalkylation effectively converted to enamides and enecarbamates into drug-like α-branched chiral amines was reported. This reaction involved the regio- and stereoselective hydrometallation of an enamide or enecarbamate to generated a catalytic amount of enantioenriched alkylnickel intermediate, followed by C-C bond formation via alkyl electrophiles.

In the presence of tetrapyridinenickel dichloride and 4,4′-di-tert-butyl-2,2′-bipyridine, functionalized alkenes such as allyl acetate underwent regioselective and diastereoselective three-component addition and dicarbofunctionalization reactions with aryl iodides such as RI [R = 4-t-BuC₆H₄, Ph, 4-MeC₆H₄, 4-MeOC₆H₄, 4-FC₆H₄, 3-MeOC₆H₄, 3-MeO₂CC₆H₄, 3-F₃CC₆H₄, 3-BrC₆H₄, 3,5-(F₃C)₂C₆H₃, 4-Br-3-MeOC₆H₃, 3-Cl-5-MeO₂CC₆H₃] and tertiary alkyl iodides such as t-BuI mediated by the organic reductant tetrakis(dimethylamino)ethylene (TDAE) to yield functionalized aryl alkanes such as t-BuCH₂CHRCH₂OAc [R = 4-t-BuC₆H₄, Ph, 4-MeC₆H₄, 4-MeOC₆H₄, 4-FC₆H₄, 3-MeOC₆H₄, 3-MeO₂CC₆H₄, 3-F₃CC₆H₄, 3-BrC₆H₄, 3,5-(F₃C)₂C₆H₃, 4-Br-3-MeOC₆H₃, 3-Cl-5-MeO₂CC₆H₃] in 29-92% yields.

Highly successful tin-free, radical-mediated alkylations of α,β-unsaturated carboxylic amides have been carried out. Alkyl iodides and bromides bearing α-electron-withdrawing groups undergo selective γ-additions to diene O,N-acetals. This approach to γ-functionalization was further extended to the use of hetero groups, such as phenylsulfanyl and phenylsulfonyl species.

Tam, Teck Lip Dexter published the artcileThermoelectric Performances of n-Doped Ladder-Type Conjugated Polymers Using Various Viologen Radical Cations, Application of 1-Iodohexane, the publication is ACS Applied Polymer Materials (2021), 3(11), 5596-5603, database is CAplus.

Understanding the dopant-polymer interaction is of interest to the conducting polymer research community due to its influence on charge transport properties and also thermoelec. performance. However, studies on such interactions are often complicated by the change in polymer morphol. upon the addition of dopants. Here, we utilized sequential solution doping of a ladder-type poly(benzimidazobenzophenanthrolinedione) (BBL) via viologen radical cation salts. The strong interchain interaction in BBL prevents the infiltration of the viologen radical cations into individual BBL fibrils, thus minimizing the disruption of the polymer morphol. By changing the N-substitution (benzyl or hexyl) and counteranion (chloride or iodide) of the viologen radical cations, the dopant-polymer interaction in such a system was studied. Our results suggest that the anion-π (radical) interaction between the counteranion and BBL (BBL^–) is detrimental to the charge transport properties and thermoelec. performance of this system. This anion-π (radical) interaction between the counteranion and BBL (BBL^–) is governed by the solution state of the viologen radical cation (tightly bound anion or dimerized with loosely bound anion) during the doping process, which is controlled by the bulkiness of the N-substitution and the Lewis basicity of the counteranion. As a result, BBL doped with benzyl viologen monochloride showed the highest conductivities with reasonably high Seebeck coefficients while BBL doped with hexyl viologen monochloride showed inferior conductivities and Seebeck coefficients

Wang, Jia-Wang published the artcileNickel-Catalyzed Switchable Site-Selective Alkene Hydroalkylation by Temperature Regulation, Product Details of C6H13I, the publication is Angewandte Chemie, International Edition (2022), 61(31), e202205537, database is CAplus and MEDLINE.

A nickel-catalyzed switchable site-selective alkene hydroalkylation was reported. The selection of reaction temperatures led to protocols that provide regiodivergent hydroalkylated products starting from a single alkene substrate. This protocol allowed the convenient synthesis of α- and β-branched protected amines, both of which are important to the fields of pharmaceutical chem. and biochem. In addition, enantioenriched β-branched alkylamines can be accessed in a catalytic asym. variant. Preliminary mechanistic studies indicate that the formation of a more stable nickelacycle provides the driving force of migration. The thermodn. and kinetic properties of different reduction elimination intermediates are responsible for the switchable site-selectivity.

Zhang, Hao published the artcileDesign, Synthesis and Herbicidal Activities of Tetrahydroisoindoline-1,3-dione Derivatives Containing Alkoxycarbonyl Substituted 2-Benzoxazolinone, Application of Ethyl 2-Iodopropionate, the publication is Chinese Journal of Chemistry (2015), 33(7), 749-755, database is CAplus.

Several different alkoxycarbonyl-substituted 2-benzoxazolinone moieties were incorporated into a tetrahydroisoindoline-1,3-dione scaffold to provide 25 compounds (1,3-dioxo-4,5,6,7-tetrahydroisoindol-2(3H)-yl)-6-halo-alkoxycarbonyl benzoxazolinones e.g., I. The structures of these compounds were confirmed by ¹H and ¹³C NMR, HRMS and X-ray single-crystal diffraction. Some of these compounds I [R = Me propanoate, Et propanoate, ethyl-2-butanoate, ethyl-4-butanoate] exhibited excellent herbicidal activities against Abutilon theophrasti, Amaranthus retroflexus and Echinochloa crus-galli at a rate of 375 g AI·ha^-1. Among them, compounds I [R = Et propanoate, ethyl-2-butanoate] displayed the best post-emergence herbicidal effect against Abutilon theophrasti with ED₅₀ values of 1.8 and 5.3 g AI·ha^-1, resp., which are superior to that of the com. acifluorfen (44.3 g AI·ha^-1). Field trials demonstrated that compound I [R = Et propanoate] exhibited similar herbicidal activity to a high concentration atrazine, and found to be safer for maize than atrazine. The results of this study therefore show that compound I [R = Et propanoate] could potentially be used as a post-emergence herbicide for maize fields.
