Autor: James A. Isaac, Gisèle Gellon, Florian Molton, Christian Philouze, Nicolas Le Poul, Catherine Belle, Aurore Thibon-Pourret

Publikováno v: Inorganics, Vol 11, Iss 8, p 332 (2023)

Copper–oxygen adducts are known for being key active species for the oxidation of C–H bonds in copper enzymes and their synthetic models. In this work, the synthesis and spectroscopic characterizations of such intermediates using dinucleating lig

Electrocatalytic reduction of CO2 in water by a C-functionalized Ni–cyclam complex grafted onto carbon

Autor: Amélie Forget, Matthieu Regnacq, Christophe Orain, Ewen Touzé, Evan Lelong, Christophe Brandily, Hélène Bernard, Raphaël Tripier, Nicolas Le Poul

Publikováno v: Chemical Communications (1359-7345) (Royal Society of Chemistry (RSC)), 2022, Vol. 58, N. 48, P. 6785-6788

We present here a novel strategy based on the covalent grafting of a C-functionalized Ni–cyclam complex onto glassy carbon to achieve heterogeneous electrocatalytic CO2 reduction in neutral water at low overpotential (−500 mV vs. NHE), with moder

Bioinspired Heterobimetallic Photocatalyst (RuIIchrom−FeIIIcat) for Visible-Light-Driven C–H Oxidation of Organic Substrates via Dioxygen Activation

Autor: Nicolas Le Poul, Tapas Goswami, Franck Thétiot, Sushil Kumar, Divyanshu Nautiyal, Arun Kumar, Siddhant Singh

Publikováno v: Inorganic Chemistry. 60:16059-16064

We report a bioinspired heterobimetallic photocatalyst RuIIchrom-FeIIIcat and its relevant applications toward visible-light-driven C-H bond oxidation of a series of hydrocarbons using O2 as the O-atom source. The RuII center absorbs visible light ne

Tungsten and molybdenum dinitrogen complexes supported by a pentadentate tetrapodal phosphine ligand: comparative spectroscopic, electrochemical and reactivity studies

Autor: Jannik Junge, Sven Froitzheim, Tobias A. Engesser, Jan Krahmer, Christian Näther, Nicolas Le Poul, Felix Tuczek

Publikováno v: Dalton transactions (Cambridge, England : 2003). 51(16)

The tungsten dinitrogen complex [W(N2)(PMe2PPPh2)] is compared to its molybdenum analogue. Detailed (IR-spectro)electrochemical investigations were made. In the presence of SmI2/H2O the W complex mediates the conversion of N2 to 2.75 equiv. ammonia.
