Metal‐organic framework derived porous structures towards lithium rechargeable batteries

EcoMat, Volume 5, Issue 2, February 2023., 2023
In this review, we discuss the characteristics of metal‐organic frameworks (MOFs) applied to lithium storage devices containing Li‐ion, Li‐sulfur, Li‐metal, and Li‐O2. We summarize the origin, nomenclature, and synthesis method of MOFs, and report on recent studies in which MOFs and MOF‐derived materials are applied to lithium rechargeable batteries ...

Continuous flow synthesis of some 6- and 1,6-substituted 3-cyano-4-methyl-2-pyridones [PDF]

Journal of the Serbian Chemical Society, 2019
In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to those achieved within classical ...

Rhodium(I)-Complexes Catalyzed 1,4-Conjugate Addition of Arylzinc Chlorides to N-Boc-4-pyridone

Molecules, 2017
Rhodium(I)-complexes catalyzed the 1,4-conjugate addition of arylzinc chlorides to N-Boc-4-pyridone in the presence of chlorotrimethylsilane (TMSCl). A combination of [RhCl(C2H4)2]2 and BINAP was determined to be the most effective catalyst to promote ...

Inductive Production of the Iron-Chelating 2-Pyridones Benefits the Producing Fungus To Compete for Diverse Niches

mBio, 2021
Diverse 2-pyridone alkaloids have been identified with an array of biological and pharmaceutical activities, including the development of drugs. However, the biosynthetic regulation and chemical ecology of 2-pyridones remain largely elusive.

Indirect Anti‐Markovnikov Hydrofunctionalization of Terminal Alkenes via an Alkenyl Thianthrenium Intermediate

Angewandte Chemie, EarlyView.
A two‐stage dication pool strategy using alkenyl thianthrenium intermediates has been developed for anti‐Markovnikov hydrofunctionalization. This method differs from previous approaches in its reaction mechanism and addresses their most significant limitation, namely, the restricted generality of the nucleophile. The approach has been extended to other

Isoselenourea‐Catalyzed Enantioselective Pyrazolo‐Heterocycle Synthesis Enabled by Self‐Correcting Amide and Ester Acylation

Angewandte Chemie, EarlyView.
A highly enantioselective isoselenourea catalyzed route to fused pyrazolo‐pyridone and ‐pyranone heterocycles has been developed. Mechanistic and computational studies highlight the significance of an intermediate amide or ester product derived from 1,2‐addition that can be diverted to the desired pathway through isoselenourea acylation.

catena-Poly[[[(2-pyridone-κO)silver(I)]-μ-2-pyridone-κ2O:O] hexafluoridophosphate]

Acta Crystallographica Section E, 2010
The asymmetric unit of the polymeric title salt, {[Ag(C5H5NO)2]PF6}n, comprises an AgI cation (located on a twofold axis), two 2-pyridone ligands (with distinct coordination modes), and half a PF6− anion (situated on a centre of inversion). The

Reverse Regioselective Dicarbofunctionalization via Anti‐Michael‐Type Addition

Angewandte Chemie, EarlyView.
A reverse regioselective dicarbofunctionalization of acrylamides via anti‐Michael‐type addition is reported. Various (hetero)arene nucleophiles and carbon electrophiles were incorporated in a manner opposite to conventional regioselectivity. A key feature of this reaction is the formation of an alkylpalladium intermediate, which enables the achievement
