• synthesis
  • This thesis describes the synthesis and characterisation of novel complexes bearing monoanionic phenolateamine ligands and explores their catalytic behaviour in the ring opening polymerisation of lactide and in the polymerisation of ethylene. (bl.uk)
  • The synthesis and characterisation of several novel main group complexes (K, Ca and Al) using these ligands is presented. (bl.uk)
  • After a brief introduction to the field of olefin polymerisation, Chapter 4 describes the synthesis and characterisation of a wide range of transition metal complexes (Ti, V, Cr, Fe, Co and Ni) and discusses their activity as precatalysts in the polymerisation of ethylene. (bl.uk)
  • These ethylhexanoate complexes are used in organic and industrial chemical synthesis. (wikipedia.org)
  • novel
  • Novel 3-O-1,2;5,6-di-O-isopropylidene-alpha-D-glueofuranose] and 3-O-D-glucose] derivatives with an iminodiacetate (N,O,O), a histidinate, and an N-(acetetyl)picolylamine (N,N,O) chelating system for tridentate coordination of the organometallic M(CO)(3)-fragment (M = Tc, Re) have been prepared.

  • catalysts
  • Coordination complexes are constantly sought as catalysts in the transformation of small molecules involved in contemporary energy and environmental challenges. (pnas.org)
  • The world of coordination complexes is currently stimulated by the quest for efficient catalysts for the electrochemical reactions underlying modern energy and environmental challenges. (pnas.org)
  • reversible
  • Originally, a complex implied a reversible association of molecules, atoms, or ions through such weak chemical bonds. (wikipedia.org)
  • The emission intensity of an indolyl maleimide derivative increases similar to 80-fold by reversible coordination to (1,4,7,11-tetraazacyclododecane) zinc(II), which makes the system a promising new signalling motif for molecular sensors. (uva.nl)
  • reactions
  • RESULTS AND DISCUSSION The reactions between the ruthenium(II) complexes and excess Co(III) concentrations follow first order kinetics in the reductants. (scribd.com)
  • different
  • The selective mitochondrial localisation of the Λ enantiomer of three different emissive europium( III ) complexes in NIH 3T3 and MCF7 cells contrasts with the behaviour of the Δ enantiomer, for which a predominant lysosomal localisation was observed by confocal microscopy. (rsc.org)
  • In a typical complex, a metal ion is bonded to several donor atoms, which can be the same or different. (wikipedia.org)
  • The first was that Werner described the two different ion possibilities in terms of location in the coordination sphere. (wikipedia.org)
  • solution
  • Nitritopentaamminecobalt(III) chloride is prepared by treating chloropentamminecobalt chloride with sodium nitrite: [Co(NH3)5Cl]2+ + NO2− → [Co(NH3)5(ONO)]2+ + Cl− Heating a solution of the nitrito complex gives the nitro isomer. (wikipedia.org)
  • species
  • A hydrated ion is one kind of a complex ion (or simply a complex), a species formed between a central metal ion and one or more surrounding ligands, molecules or ions that contain at least one lone pair of electrons, If all the ligands are monodentate, then the number of donor atoms equals the number of ligands. (wikipedia.org)
  • center
  • The NMR, MS, and IR analyses corroborated the tridentate coordination of the organometallic metal center exclusively via the synthetic chelates. (uzh.ch)
  • properties
  • In the case of the N-(acetyl)picolylamine derivative, the coordinative properties were further confirmed by X-ray structure analysis of the first Re(CO)(3)-D-glucofuranose complex. (uzh.ch)
