Kinetic analysis of Copper(I)/Feringa-Phosphoramidite Catalysed AlEt3 1,4-Addition to Cyclohex-2-en-1-one (2017)
Journal Article

ReactIR studies of mixtures of AlEt3 (A) and cyclohex-2-en-1-one (CX) in Et2O indicate immediate formation of the Lewis acid-base complex (CX.A) at -40 oC (K = 12.0 M-1, ΔGoreact -1.1 kcal mol-1). Copper(I) catalysts, derived from pre-catalytic Cu(OA... Read More about Kinetic analysis of Copper(I)/Feringa-Phosphoramidite Catalysed AlEt3 1,4-Addition to Cyclohex-2-en-1-one.

Probing the electronic environment of binary and ternary ionic liquid mixtures by x-ray photoelectron spectroscopy (2017)
Journal Article

X-ray photoelectron spectroscopy is used to probe the electronic environment of cations and anions for three binary and one ternary chlorostannate ionic liquid mixtures. The impact of the weighting of Cl on the electronic environment of the cation-b...

A Simple Approach to the Visible-Light Photoactivation of Molecular Metal Oxides (2017)
Journal Article

© 2017 American Chemical Society. This study explores a new method to maximize the visible-light-driven photocatalytic performance of organic-inorganic hybrid polyoxometalates (POMs). Experimental and theoretical investigations of a family of phospho... Read More about A Simple Approach to the Visible-Light Photoactivation of Molecular Metal Oxides.

Efficient synthesis of 2,5-dicarbonyl derivatives of 3,4-ethylenedithiothiophene (EDTT) via addition-elimination reaction (2017)
Journal Article

Derivatives of 3,4-ethylenedithiothiophene (EDTT) are reported starting from tetrabromothiophene. Selective 2,5-dilithiation followed by reaction with a range of aldehydes gives diols as mixtures of diastereomers. Only the 2 and 5 positions in thioph...

Valorisation of lignin by depolymerisation and fractionation using supercritical fluids and conventional solvents (2017)
Journal Article

A procedure for Lignosulphonate valorisation is investigated. An attempt has been made to obtain diverse value-added products maximizing the atom economy. This procedure is carried in sequential steps starting with an oxidative depolymerization in su...

Covalent organic frameworks and organic cage structures (2017)
Journal Article

The last 20 years have seen an enormous interest in research on the topic of crystalline porous framework materials, especially metal–organic frameworks (MOFs). MOFs exploit reversible metal–coordination chemistry to create extended, crystalline soli... Read More about Covalent organic frameworks and organic cage structures.

Electroanalysis of neutral precursors in protic ionic liquids and synthesis of high-ionicity ionic liquids (2017)
Journal Article

Protic ionic liquids (PILs) are ionic liquids that are formed by transferring protons from Brønsted acids to Brønsted bases. While they nominally consist entirely of ions, PILs can often behave as though they contain a significant amount of neutral...

Ci-Symmetry, [2 × 2] grid, square copper complex with the N4,N5-bis(4-fluorophenyl)-1H-imidazole-4,5-dicarboxamide ligand: structure, catecholase activity, magnetic properties and DFT calculations (2017)
Journal Article

A new square tetranuclear copper complex of formula Cu4(LH)4·4DMF with the dinucleating amide ligand N4,N5-bis(4-fluorophenyl)-1H-imidazole-4,5-dicarboxamide (LH3) is reported herein. This ligand and the complex have been characterized by elemental a...

Structure determination techniques flex their muscles (2017)
Journal Article

A historical challenge: Gas-phase electron diffraction and single-crystal X-ray diffraction are both established techniques, but they were both pushed to their limits by the challenge posed by the highly flexible tetranitromethane molecule. New appro... Read More about Structure determination techniques flex their muscles.

Visible Light Production of Hydrogen by Ablated Graphene: Water Splitting or Carbon Gasification? (2017)
Journal Article

Reduced graphene oxide modified by pulsed laser ablation causes water splitting under visible light illumination (532 nm). When the light source is a pulsed laser, water splitting is accompanied by carbon gasification (CO formation); however, convent...
