A rhenium-based photocatalyst enables the deoxygenation of several compounds containing N–O bonds, such as N2O and pyridine N-oxides.
UNLABELLED We proposed a new water-soluble rhenium diseleno-ether compound (with one atom of Re and two atoms of Se) and investigated the uptake of Re into the nucleus of malignant cells in culture exposed to the compound for 48 h and its efflux from the nucleus after a post-exposure period of 48 h, as DNA is the main target of Re. We also studied the distribution of both Re and Se in the main ...
In situ prepared lithium arylselenolates {LiSePh, LiSe(2,6-Me2Ph), LiSe(2,4,6-Me3Ph)} or -tellurolates {LiTePh, LiTe(2,6-Me2Ph), LiTe(2,4,6-Me3Ph)} react with [ReOCl3(PPh3)2] and (NBu4)Br in good yields under formation of rhenium(V) complexes the composition (NBu4)[ReO(L)4)]. The first oxidorhenium(V) complex four monodentate phenolato ligands, [ReO(2,6-Me2Ph)4]?, was isolated crystalline form....
On-demand production of hydrogen from ammonia is a challenge limiting the implementation as long term vector to overcome difficulties associated with storage. Herein, we present development catalysts for on-demand by combining metals high and low N-adatom adsorption energies. In this way, cobalt-rhenium (Co-Re) show activity mimicking that ruthenium. EXAFS/XANES analyses demonstrate bimetallic ...
