Iron-oxalato framework with one-dimensional open channels for electrochemical sodium-ion intercalation.

Chemistry (Weinheim an der Bergstrasse, Germany)

Wang X, Kurono R, Nishimura S, Okubo M, Yamada A.
PMID: 25404228
Chemistry. 2015 Jan 12;21(3):1096-101. doi: 10.1002/chem.201404929. Epub 2014 Nov 17.

Discovery of a new class of ion intercalation compounds is highly desirable due to its relevance to various electrochemical devices, such as batteries. Herein, we present a new iron-oxalato open framework, which showed reversible Na(+) intercalation/extraction. The hydrothermally synthesized...

JDR Clin Trans Res. 2018 Jan;3(1):76-82. doi: 10.1177/2380084417742099. Epub 2017 Nov 13.

Dentinal hypersensitivity (DH) can have a significant impact on oral health and functioning, and it is a clinical symptom commonly managed by dentists during routine clinical practice. DH symptoms are typically elicited by otherwise innocuous, nonpainful stimuli applied to...

Alcohols as Latent Coupling Fragments for Metallaphotoredox Catalysis: sp.

Journal of the American Chemical Society

Zhang X, MacMillan DWC.
PMID: 27718570
J Am Chem Soc. 2016 Oct 26;138(42):13862-13865. doi: 10.1021/jacs.6b09533. Epub 2016 Oct 17.

Alkyl oxalates, prepared from their corresponding alcohols, are engaged for the first time as carbon radical fragments in metallaphotoredox catalysis. In this report, we demonstrate that alcohols, native organic functional groups, can be readily activated with simple oxalyl chloride...

Ni-Catalyzed Reductive C-O Bond Arylation of Oxalates Derived from α-Hydroxy Esters with Aryl Halides.

Organic letters

Org Lett. 2019 Mar 15;21(6):1645-1648. doi: 10.1021/acs.orglett.9b00174. Epub 2019 Feb 25.

A Ni-catalyzed reductive cross-coupling of α-hydroxycarbonyl compounds modified with oxalyl groups and aryl halides has been developed that furnishes α-aryl esters under mild conditions and tolerates a variety of functionalized aryl halides bearing electron-withdrawing and -donating groups. This work...

Phytochemicals enhance human health by acting antagonistically on incidences of cancer and other chronic diseases. They are considered indispensable in a variety of nutraceutical, pharmaceuticals, and medicinal and cosmetic applications. This study evaluated the effects of common processing methods...

Three-component 1,2-dicarbofunctionalization of alkenes involving alkyl radicals.

Chemical communications (Cambridge, England)

Gao P, Niu YJ, Yang F, Guo LN, Duan XH.
PMID: 34931629
Chem Commun (Camb). 2022 Jan 18;58(6):730-746. doi: 10.1039/d1cc05730h.

1,2-Dicarbofunctionalization of alkenes represents an appealing strategy for chemical bond formation in organic synthesis, which could enable the rapid construction of molecular complexity from simple and readily available starting materials by incorporating two functional groups onto a carbon-carbon double...

In Search of an Efficient Complexing Agent for Oxalates and Phosphates: A Quantum Chemical Study.

Nanomaterials (Basel, Switzerland)

Limiting gastrointestinal oxalate absorption is a promising approach to reduce urinary oxalate excretion in patients with idiopathic and enteric hyperoxaluria. Phosphate binders, that inhibit gastrointestinal absorption of dietary phosphate by the formation of easily excretable insoluble complexes, are commonly...
