Sodium thioether macrocyclic chemistry: remarkable homoleptic octathia coordination to Na(+).
Unprecedented homoleptic octathioether macrocyclic coordination to Na(+) in [Na([24]aneS8)](+) has been achieved by using Na[B{3,5-(CF3)2-C6H3}4] as a source of "naked" Na(+) ions and confirmed crystallographically, with d(Na-S) = 2.9561(15)-3.0524(15) Å. Density functional theory calculations show that there is electron transfer from the S 3p and C 2p valence orbitals of the ligand to the 3s a...

متن کاملHomoleptic pnictogen-chalcogen coordination complexes.
The synthesis and structural characterization of dicationic selenium and tellurium analogues of the carbodiphosphorane and triphosphenium families of compounds are reported. These complexes, [Ch(dppe)][OTf](2) [Ch = Se, Te; dppe = 1,2-bis(diphenylphosphino)ethane; OTf = trifluoromethanesulfonate], are formed using [Ch](2+) reagents via a ligand-exchange protocol and represent extremely rare exa...
متن کاملPentadentate thioether-oxime macrocyclic and quasi-macrocyclic complexes of copper(II) and nickel(II)
A series of new pentadentate thioether-oximes (TtoxH2, MeTtoxH2, OdtoxH2) were synthesized along with their Ni(II) and Cu(II) complexes. BF2 -bridging is accomplished by reaction of the H-bonded oxime complex with BF3·OEt2, though when Cu(BF4)2 is used as the Cu(II) salt, direct macrocyclization occurs during the metal complexation reaction. Crystallographic studies reveal: [Cu(TtoxH)]ClO4 has ...
متن کاملThioether-based anchimeric assistance for asymmetric coordination chemistry with ruthenium(II) and osmium(II).
(R)-4-(alkylthiomethyl)-5,5-dimethyl-2-(2'-hydroxyphenyl)-2-oxazolines are demonstrated to be highly suitable chiral auxiliaries for the two-step conversion of the half-sandwich complex [Ru(η(6)-C6H6)(bpy)Cl]Cl, bpy = 2,2'-bipyridine, into Δ-configured ruthenium polypyridyl complexes. The tailored thioether substituent at the oxazoline ring is essential for this conversion and not only promotes...
