    Pyridine–oxazoline and quinoline–oxazoline ligated cobalt complexes: Synthesis, characterization, and 1,3-butadiene polymerization behaviors
    摘要:
    A series of cobalt complexes supported by pyridine-oxazoline (Pyox) and quinoline-oxazoline (Quox) were synthesized. Determined by single crystal X-ray crystallography, complexes 6a and 7c adopted distorted octahedron and trigonal bipyramid geometries, respectively, while complex 6b existed as an ion pair comprised of [CoL2](2+) and [CoCl4](2-), in which the cationic and anionic moieties displayed distorted octahedron and tetrahedral geometries, respectively. Upon activation with ethylaluminium sesquichloride (EASC), these cobalt complexes exhibited high catalytic activity and cis-1,4-selectivity toward 1,3-butadiene polymerization. The selectivity of the catalytic system could be switched from cis-1,4 to 1,2-fashion via the addition of PPh3. The effects of ligand environment, polymerization temperature, and [Al]/[Co] ratio on the polymerization were investigated in detail. (C) 2015 Elsevier B.V. All rights reserved.

  • Synthesis and evaluation of the in vitro DNA-binding properties of chiral<i>cis</i>-dichloro(pyridyloxazoline)platinum(II) complexes

    A series of chiral cis-dichloro(pyridyloxazoline)platinum(II) and palladium(II) complexes were synthesized and their reactivity towards a defined sequence of single-stranded and double-stranded DNA was investigated in comparison to cisplatin. The compounds differed in the nature and absolute configuration of the substituent at the C4 position of the oxazoline ring. The DNA-binding ability of these compounds was evaluated by HPLC analysis, post metal exposure, of enzymatic digests of an undecamer duplex containing one putative metallation site. Polyacrylamide gel electrophoresis (PAGE) and thermal denaturation confirmed the results of the HPLC analysis, which showed that the stereochemistry and character of the substituent at the C4 position of the oxazoline ring had little effect on DNA binding, possibly due to the formation of monofunctional adducts.Key words: cisplatin, chiral, pyridyloxazoline, DNA-binding studies, platinum, palladium.

  • Arene ruthenium complexes with pyridyloxazolines: synthesis and applications as asymmetric catalysts for Diels–Alder reactions †

    Reaction of the dimers [RuCl2(arene)]2 with pyridyloxazolines (pymox) gave complexes [RuCl(pymox)(arene)][SbF6] 1–12 which have been fully characterised. Using chiral ligands diastereomers are formed, the diastereoselectivity depending on the substituents on the arene and on the oxazoline. The complexes [RuCl(Me2-pymox)(mes)][SbF6] 1, [RuCl(Ph-pymox)(mes)][SbF6] 3, [RuCl(iPr-pymox)(mes)][SbF6] 5 and [RuCl(indanyl-pymox)(mes)][SbF6] 12 (mes = mesitylene) have been characterised by X-ray crystallography. Treatment of these cations with AgSbF6 generates dications which in some cases can be isolated as aqua species [Ru(OH2)(pymox)(arene)]2+; these dications are enantioselective catalysts for Diels–Alder reactions of acroleins and dienes; a mechanism is proposed which accounts for the observed enantioselectivity.
