Synthesis and crystal structure of the η^2–bonded CSe₂ complex [(triphos )RhCl(η^2–CSe₂)]·C₆H₆triphos =(Ph₂PCH₂)₃CMe]. Metal-promoted head-to-head dimerization of CSe₂ to C₂Se₄

Abstract

The reaction of CS₂with [RhCl(C₂H₄)₂]₂ and triphos [triphos =(Ph₂PCH₂)₃CMe] give [(triphos)RhCl(η²CSe₂)]·C₆H₆,X-ray analysis of which shows that CSe₂ is η^2–bonded via C and Se; the action of Lewis acids on this η^2–CSe₂Compound leads to the unpuecedented ethenetetraselenolat-bridged complexes [(triphos)Rh(µ-C₂Se₄)Rh(triphos)]Y₂(Y [double bond, length half m-dash] Cl, BF₄,PF_6,or BPh₄).
