NiII complexes of the new pincer amidobis(amine) ligand are described. The Ni chloride complex catalyzes Kumada-Corriu-Tamao coupling of unactivated alkyl halides with alkyl Grignard reagents, as well as double C-C coupling of CH2Cl2 with alkyl Grignard re ...
The cationic complexes [(η6-arene)Ru(SC5H4NH)3]2+, arene being C6H6 (1), MeC6H5 (2), p-iPrC6H4Me (3) or C6Me6 (4), have been synthesized from the reaction of 4-pyridinethiol with the corresponding precursor (η6-arene)2Ru2(μ2-Cl)2Cl2 and isolated as the chl ...
Metal ions are constituents of many metalloproteins, in which they have either catalytic (metalloenzymes) or structural functions. In this work, the characteristics of various metals were studied (Cu, Zn, Mg, Mn, Fe, Co, Ni, Cd and Ca in proteins with know ...
Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...
The silver, copper and gold complexes of tripodal N-heterocyclic carbene (NHC) ligand, 1,1,1-tris[(3-methylimidazol-1-yl-2-ylidene)methyl]ethane were prepd. and characterized. The silver complex of the title ligand, TIMEMe was prepd. by reaction of [H3TIME ...
The labile cobalt (II) complex [Co(TUF)2(Pic)2] with 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (TUF) bidentate and 4-methylpyridine (Pic) monodentate ligands was studied by variable temp. (VT) 19F NMR from 184 to 312 K. In contrast to the solid state, ...
The thermochem. of the RuO42- + MnO4- RuO4- + MnO42- redox reaction in aq. soln. is studied by sep. d.-functional-based ab initio mol.-dynamics simulations of the component half reactions RuO42- -> RuO4- + e- and MnO42- -> MnO4- + e-. We compare the result ...
The hexadentate bispidine-based ligand 2,4-bis(2-pyridyl)-3,7-bis(2-methylenepyridine)-3,7-diazabicyclo[3.3.1]nonane-9-on-1,5-bis(carbonic acid methyl ester), L-6m, with four pyridine and two tertiary amine donors, based on a very rigid diazaadamantane-der ...
The nature of the bonding in ethylene and h2-P4 complexes, M(C2H4)2+ and M(h2-P4)2+, of group 11 metal cations (M = Cu, Ag, Au) has been explored by d. functional calcns. On the basis of the evaluation of symmetry orbitals, the contributions from the inter ...
The assisted transfer of silver ion, Ag+, by complexation of Ag+ with the tetrakis(4-chlorophenyl)borate (TPBCl−) anion was studied at the interface between two immiscible electrolyte solutions (ITIES). The elucidation of the interfacial mechanisms employe ...
