Mission Statement

ChemPubSoc Europe is an organization of 16 European chemical societies, founded in the late 1990s as a consequence of the amalgamation of many chemical journals owned by national chemical societies into a number of high-quality European journals.

ChemPubSoc Europe's journals, all published with Wiley-VCH, are: Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemBioChem, ChemPhysChem, ChemMedChem, ChemSusChem, ChemCatChem, ChemPlusChem, ChemElectroChem, ChemistryOpen, and ChemViews, the ChemPubSoc Europe e-zine. They replaced 16 traditional national chemistry journals.

The participating societies share a commitment to scientific excellence, to publishing ethics, and to the highest standards in publication, which are the basis for the success of the ChemPubSoc Europe journals.

ChemPubSoc Europe and its Asian sister organization, the Asian Chemical Editorial Society (ACES), mutually support each other in the publication of their journals Chemistry—A European Journal, Chemistry—An Asian Journal, and ChemSusChem.

A Base-Mediated Mild Sulfenylation of Indoles and Pyrrole with α-Acylthiones

A Base-Mediated Mild Sulfenylation of Indoles and Pyrrole with α-Acylthiones

A simple procedure for the sulfenylation of indoles and pyrroles through hetero-aromatic substitution with α-acylthiones acting as electrophiles is presented. The reaction occurs under mild basic conditions that are particularly suitable for the derivatization of aza-aromatics. However, such conditions are quite uncommon.

Highly Stereoselective Nucleophilic Addition of Difluoromethyl-2-pyridyl Sulfone to Sugar Lactones and Efficient Synthesis of Fluorinated 2-Ketoses

Highly Stereoselective Nucleophilic Addition of Difluoromethyl-2-pyridyl Sulfone to Sugar Lactones and Efficient Synthesis of Fluorinated 2-Ketoses

Nucleophilic addition of difluoromethyl-2-pyridyl sulfone to sugar lactones gave intermediates that are stable and capable of useful conversions. Formal elimination of the anomeric hydroxy and sulfonyl groups yielded a 1-deoxy-1-difluoromethylene mannopyranose derivative. Fluorinated 2-ketose analogues were prepared by a one-pot reduction with allylmagnesium chloride.

Dissymmetric difunctionalised 9,9'-spirobifluorene derivatives were prepared and resolved by HPLC on a chiral stationary phase on a semipreparative scale. The absolute configurations of the resolved enantiomers were assigned by comparison of specific optical rotations with literature data or retention times of independently prepared enantiomerically pure material.

Mild, Stereoselective, and Highly Efficient Synthesis of N-Acylhydrazones Mediated by CeCl3·7H2O in a Broad Range of Solvents

The stereoselective condensation of hydrazides with aldehydes or ketones to give (E)-N-acylhydrazones is a valuable approach to prepare new compounds that exhibit biological activity. A mild, easy, environmental friendly, and highly efficient method that employs CeCl3·7H2O as the catalyst was developed to provide a broad and structurally diverse library of N-acylhydrazones in excellent yields.

Unusual Solvent Dependence of a Molecule-Based FeII Macrocyclic Spin-Crossover Complex

Unusual Solvent Dependence of a Molecule-Based FeII Macrocyclic Spin-Crossover Complex

The solvent dependence of spin-crossover behavior and metastability of the FeII complex [FeL222N3O2(CN)2]·H2O were investigated. Compared with the pristine and the dehydrated complex, the rehydrated complex shows enhanced metastability and an increased spin-transition temperature. This solvent dependence indicates new possibilities to improve metastability toward further applications.

Main-Chain Oligomers from NiII- and CuII-Centered Unsymmetrical N2O2 Schiff-Base Complexes: Synthesis and Spectral, Structural, and Second-Order Nonlinear Optical Properties

The esterification of binuclear phenol and carboxylic acid functionalized ferrocenyl-containing metal-centered Schiff-base complexes (M = Ni, Cu) in the presence of N,N'-dicyclohexylcarbodiimide and dmap afforded their corresponding main-chain oligomers. They are formed of approximately six monomeric units, are redox active, and exhibit good thermal stability and high second-order NLO responses.

Evolution of the Coordination-Sphere Symmetry in Copper(II), Nickel(II), and Zinc(II) Complexes with N,N'-Double-Armed Diaza-Crown Ethers: Experimental and Theoretical Approaches

Symmetric versus asymmetric octahedral coordination geometry changes were observed for Cu2+, Ni2+, and Zn2+ complexes of a N,N'-triazolyl-biarmed diaza[18]crown-6 macrocycle. Quantum chemical calculations at the DFT level confirmed these observations and allowed us to interpret them in terms of covalent or noncovalent metal–ligand interactions.

Environmentally-Friendly Lithium Recycling From a Spent Organic Li-Ion Battery

Pre-loved lithium: A simple method is investigated for recycling lithium from organic electrode materials for secondary lithium batteries. The method uses non-polluting solvents and a single thermal treatment step at moderate temperature. Up to 99 % of the capacity is retained with the recycled materials. Moreover, only a moderate quantity of lithium is lost during the course of the complete procedure.

Alkali-metal ion catalysis and inhibition in SNAr displacement: The SNAr reaction of aryloxy-2,4-dinitrobenzenes with alkali metal ethoxides proceeds through a stepwise mechanism via a π-complexed transition state. Alkali metal ions catalyze or inhibit SNAr reactivity depending on the relative stabilization of the ground state (GS) and transition state (TS) complexes.

Rapid Assembly of Functionalised Spirocyclic Indolines by Palladium-Catalysed Dearomatising Diallylation of Indoles with Allyl Acetate

Heterocycles: We report the application of allyl acetate to the palladium-catalysed dearomatising diallylation of indoles. The reaction can be carried out by using a readily available palladium catalyst at room temperature, enabling substituted indoles to be converted into 3,3-diallylindolinines. These compounds are versatile synthetic intermediates that can be elaborated into a range of scaffolds including functionalised spirocyclic indolines and dihydrocarbazoles (see scheme).
