Herein we report a dinickel azacryptand complex that enables fast, selective, and tight CO2 binding from air. Exploiting the affinity of the cavitand towards azides, CO2 release was observed. Despite the stability of the azido complex, UV irradiation under atmospheric conditions proved to be a suitable pathway for N3(-) replacement by CO2.
A series of coordination compounds has been prepared comprising manganese, iron, nickel, and zinc bound by a hexaanionic cryptand where carboxamides are anionic N-donors. The metal complexes have been investigated by X-ray crystallography, and possess metal centers in trigonal monopyramidal geometries with intermetallic distances spanning d(Mn,avg) = 6.080 Å to d(Ni,avg) = 6.495 Å. All complexe...
abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
This review focuses on the chemical methods used to prepare supported bimetallic heterogeneous catalysts, i.e., bimetallic nanoparticles deposited on a support. The review is limited to the preparation of gold-based bimetallic catalysts and moreover to bimetallic nanoparticles supported on powder inorganic supports, i.e., on the surface or in the porosity, and not on model supports such as sing...
New aluminium complexes containing bis-BTP ligands (BTP = N,O-bidentate benzotriazole phenoxide) were synthesized and structurally characterized. Amine elimination of Al(NMe2)3 with (R)BTP-H ligands ((CMe2Ph)BTP-H = 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol, (t-Bu)BTP-H = 2-(2H-benzotriazol-2-yl)-4,6-di-tert-butylphenol and (TMCl)BTP-H = 2-tert-butyl-6-(5-chloro-2H-benzotri...
The purpose of the present review is to provide an overview about the synthesis, characterization techniques involved and various physico-chemical properties of quinoxaline derivative metal complexes reported upto 2006 by several researchers. The synthesis of variety of metal complexes such as mono, bi and trimetallic complexes, homo bimetallic complexes, polynuclear, mixed metal and mixed liga...
Abstract The reactions of the N‐heterocyclic carbene‐parent phosphinidene adducts (IMes)PH ( 1 a ) and (IDipp)PH b with one equivalent copper(I) or silver(I) chloride afforded monometallic complexes [{(IMes)PH}MCl] 2 , M=Cu; M=Ag) [{(IDipp)PH}MCl] 3 M=Ag). Single‐crystal X‐ray diffraction analyis provided evidence for higher tendency ligand to form polynuclear structures bridging NHC‐phosphinid...
Bimetallic dendrimer-encapsulated nanoparticles (DENs) are important materials, because they have demonstrated improvement in performance compared to the monometallic DENs in many systems when they are used as catalysts. This tutorial review focuses on the recent research advances in bimetallic DENs with respect to their synthesis, characterization, and applications as catalysts. Bimetallic DEN...
