Reactivity of Cu(I) nacnac complexes towards [Cp*Ru(η⁵-E₅)] (E = P, As)

Abstract

The reactivity of the nacnac Cu(I) compound [L²Cu(MeCN)] (2) (L² = [{N(C₆H₃Me₂-2,6)C(Me)}₂CH]^-) towards complexes containing aromatic cyclo-E₅ ligands (E = P, As) was investigated. The copper complex was reacted with [Cp*Ru(η⁵-E₅)] (E = P (1a-Ru), As (1b-Ru)), yielding the heterometallic complexes [(Cp*Ru)(μ,η^5:2-E₅)(L²Cu)] (E = P (3a), As (3b)). These neutral and molecular complexes represent rare examples of the coordination of group 11 metal complexes to cyclo-E_n units and are also rare examples of the coordination compounds of 1a-Ru and 1b-Ru. They were fully characterized by crystallographic and spectroscopic methods and compared to related compounds.
