Presentation

L’IRSAMC (The Institute of Research on Complex Atomic and Molecular Systems) is a federation of four laboratories (LCAR, LCPQ, LPCNO, LPT), in physics and fundamental chemistry whose research activities are supported both by the Université Paul Sabatier, the CNRS and INSA

Publications of 4 research laboratories

  • Hal-LCAR. - Laboratory Collisions Clusters Reactivity, from 1990 until todays
  • Hal-LCPQ. - Quantum Chemistry and Physics Laboratory, from 2007 until todays
  • Hal-LPCNO. - Physics and Chemistry of Nano Objects Laboratory, from 2006 until todays
  • Hal-LPT.- Theoretical Physics Laboratory, from 2003 until todays

Main advantages and functioning of Hal

Main advantages

  • Long-term archiving, sustainability of the deposits
  • Better visibility of the scientific productivity
  • Open access, accessible everywhere
  • Possibility of establishing lists of publications

Functioning

  • The deposit of a document requires the agreement of its authors, and it must respect editor policy.
  • If no agreement has been spent, deposit only the bibliographical note
  • Beware ! Once a document is put online, it cannot be withdrawn. New versions may be added.

[hal-01367220] Yb(II) Triple-Decker Complex with the μ-Bridging Naphthalene Dianion [CpBn5Yb(DME)]2(μ-η4:η4-C10H8). Oxidative Substitution of [C10H8]2- by 1,4-Diphenylbuta-1,3-diene and P4 and Protonolysis of the Yb-C10H8 Bond by PhPH2  (16/09/16)  
Two synthetic approaches to the new three-decker Yb(II) complex [CpBn5Yb(DME)]2[μ-C10H8] (1) were successfully employed: the reaction of [CpBn5Yb(DME)(μ-I)]2 (2) with 2 molar equiv of [C10H8]-·K in DME and the reaction of [YbI(DME)2]2[μ-C10H8] (3) with CpBn5K in a 1:2 molar ratio in DME. Complex 1 was proved to be a Yb(II) binuclear triple-decker complex containing a dianionic naphthalene ligand bridging two CpBn5Yb(DME) fragments in a μ- η4:η4 fashion. An oxidative substitution of (C10H8)2- by trans-(1E,3E)-1,4-diphenylbuta-1,3-diene afforded the three-decker Yb(II) complex [CpBn5Yb(DME)]2(μ- η4:η4 -PhCHCHCHCHPh) (4) with a dianionic μ- η4:η4-bridging diphenylbutadiene ligand and naphthalene. The reaction of 1 with excess P4 also occurs with oxidation of (C10H8)2-, whereas Yb remains divalent. The reaction results in the formation of the trinuclear Yb(II) complex with a μ-bridging P7 3- ligand [CpBn5Yb(DME)]3(P7) (5). Protonation of the Yb-C10H8 bond in 1 with PhPH2 (1:2 molar ratio) afforded the dimeric phosphido complex [CpBn5Yb(THF)(μ2-PHPh)]2 (6) in 64% yield, while an attempt to obtain a phosphinidene Yb(II) species by reacting equimolar amounts of 1 and PhPH2 in DME resulted in the isolation of the metallocene complex CpBn5 2Yb(DME) (7). © 2016 American Chemical Society.
