Mischmetall, an alloy of the light lanthanides, has been used in a variety of organic reactions, either as a coreductant in samarium(II)-mediated reactions (Barbier and Grignard-type reactions, pinacolic coupling reactions) or as the promoter of Reformatsky-type reactions. It has been also employed as the starting material for easy syntheses of lanthanide trihalides, the reactivity of which has...

Pour détecter des biomolécules et pathogènes (protéines, virus, bactéries, …) avec sensibilités satisfaisantes, il est actuellement nécessaire d’utiliser appareils de laboratoires coûteux. En combinant les remarquables propriétés optiques ions lanthanides à un lecteur simple couplé smartphone, nous démontrons comment développer système détection portable, rapide ultrasensible.

Lanthanides ions allows for the design of remarkable magnetic compounds with unique magnetic properties. One of their assets is that they can give rise easily to multi-functional materials. Such multi-functionality is found in the collection of papers of this Special Issue with contributions that highlight the unprecedented magnetic properties of lanthanide-based molecules together with chirali...

We present in this study a new and one-step method allowing the preparation of an unprecedented family of stable half-lanthanidocenes. X Ray analysis shows that the isolated compounds all display the same ionic Ln-Mg bimetallic structure consisting of two anionic (Cp)Ln(BH4)3 species and one cationic Mg(THF)6 (Cp = C5Me5, Ln = Nd, 1a, Ln = La, 1b; Cp = C5H5, Ln = Nd, 2a; Cp = C5H2Ph3, Ln = Nd, ...

In the present review, works on classes of chelating extractants for metals, compounds with several amide and carboxyl groups, azomethines, oximes, macrocyclic (crown ethers calixarenes), phenanthroline derivatives, others are systematized. This review focuses efficiency selectivity in recovery metals from industrial wastewater, soil, spent raw materials, separation metal mixtures. As a result ...
