The Catalytic Asymmetric Allylic Alkylation of Acyclic Enolates for the Construction of Quaternary and Tetrasubstituted Stereogenic Centres

open access: yesChemistry – A European Journal, Volume 30, Issue 20, April 5, 2024.
This review describes the catalytic asymmetric allylic alkylation (AAA) of acyclic prochiral nucleophiles, namely enolates, as a means of accessing congested quaternary and tetrasubstituted stereogenic centres. In particular, strategies for the stereocontrolled access to acyclic enolate nucleophiles, as well as the impact of enolate geometry on the ...

Electrochemical Behavior of Quinones Classically Used for Bioenergetical Applications: Considerations and Insights about the Anodic Side

open access: yesChemElectroChem, Volume 11, Issue 5, March 1, 2024.
In this article, the electrochemical behaviour of some substituted quinones (dichloro‐; dimethyl‐; phenyl) is revisited in aqueous media using chronoamperometry, cyclic and steady‐state voltammetry. In particular, the calculation of the number of electrons involved in the hydroquinone/quinone couple may be distorted due to kinetic limitations. A simple

Electrode Treatments for Redox Flow Batteries: Translating Our Understanding from Vanadium to Aqueous‐Organic

open access: yesAdvanced Science, Volume 11, Issue 1, January 5, 2024.
Electrodes are often treated chemically to mitigate the voltage losses in redox flow batteries (RFBs) and improve RFBs performance. Here, electrode treatments are compared for vanadium‐based RFBs under similar operating conditions to identify promising treatments for industrial implementation.

1,3-Bis(2,6-diisopropyl-phen-yl)-1H-imidazol-3-ium bromide dichloromethane disolvate

open access: yes, 2012
In the title compound, C27H37N2 +·Br−·2CH2Cl2, both the cation and the anion are located on a crystallographic mirror plane. Both of the dichloro­methane solvent mol­ecules show a disorder across a mirror plane over two equally occupied positions. In the
